His obsession with Mikey.
Of course, that "Mikey's obsession" was for you.
Haruchiyo was just watching and listening to you silently as you spoke eagerly.
"Look, you can see his room clearly from this angle! You already know most of his habits, though... but okay! We have a chance to learn new things about him"
Sanzu listened to you, but your words weren't penetrating his mind.
"Look, look! He went into his room! What is he doing? I can't see."
Your eyes darting around, trying to see what Mikey was doing. It was giving Sanzu quite a sight.
A teasing smirk appeared from under his mask.
"Do you need an eye doctor?"
Sanzu, this boy who normally barely smiled, was making every joke he could think of when it came to you. You looked at him in shock as he burst out laughing.
"Okay, okay, I was joking."
You couldn't help the smile that appeared on your face. As you turned your head back to the window of Mikey's room, Sanzu continued to glance at you every now and then.
Days passed like this, one by one. Every day, you helped him stalk Mikey, trying to bring the two of them closer. In your dream world, those two were a couple.
Sanzu, on the other hand, didn't realize you were shipping them, didn't even realize that you thought he likes Mikey.
He understood everything completely differently.
"I'm telling you, I'm serious, why don't you believe me yet?! It's obvious she has a crush on me!"
"How can a girl who helped you stalk Mikey be in love with you for god's sake??"
Sanzu and Mucho's voices were rising from the cafe they were sitting in. Sanzu was telling about all the "moments full of love" he had experienced with you to Mucho and waiting for him to comment about them. He was less knowledgeable about love.
"Look, she invited me to a cafe the other day, you should have seen it, I think it was a cafe where most people go for dates! Then she talked about Mikey, blah blah blah. She laughed at all the jokes I made in the cafe!!"
"As the name suggests, 'jokes', of course she was going to laugh, what did you expect?"
"Shut up, I'm not done talking yet. First we were sitting opposite each other, but then she pulled her chair over and sat next to me. While we were talking she was occasionally touching my arm and leaning on my shoulder. When we first met, she told me she wasn't someone who liked contact though!"
"So she's starting to trust you."
"So she's starting to fall in love?"
Mucho put his hand on his forehead and sighed. On the one hand, he wanted to laugh, but on the other hand, he found it cute to see Sanzu misunderstanding your every move and starting to fall for you.
"No, Haruchiyo, not every trust means love."
"But even when I first invited her over and she saw me without my mask on, she didn't judge me, she even said I looked really cute."
"Could you be a little patient-"
"I think I should kiss her when we meet tonight."
There was a long silence in between them. A vein throbbed in Mucho's temple as his eye twitched.
"What, is this too much? Pfft, but we've been going on like this for months, I'm so sick of it!"
Mucho sighed for perhaps the hundredth time, knowing he couldn't stop a Sanzu that had reached this point, so he tried to offer advice instead.
"Well... since you're so fed up, you can try other things instead of kissing her directly. Like... talking, right? It's very simple."
"Talking? You know I'm not good with words, especially around her."
"It's worth a try. You just have to say your feelings, Haruchiyo."
Sanzu's eyebrows were furrowed. Maybe it was from anger, maybe from stress. But he was definitely thinking of you, that much was obvious. Expressing his feelings was never easy for him.
But still, there was hope inside him.
Because he thought you liked him, you were in love with him.
- you're coming tonight, aren't you?
It was a message from Sanzu that appeared on your phone. You promised him that you would go to his house for dinner today.
- yupp! I'm coming. I hope you prepared some delicious meals?
- I prepared the best ones for you.
Receiving messages like these from him always put a smile on your face. Before leaving the house, you checked your appearance in the mirror one last time.
"Hey! I told you to just sit down and rest!"
"And I said I'll help you!"
That was just one of the arguments you had while you helped Sanzu set the table. Soon, you were sitting down at the table and eating together.
"Mhmm! They're delicious. Maybe you should become a chef."
"You're exaggerating, I'm not that good."
Sanzu was laughing at your compliments while eating. His mask was in his room; he'd even forgotten he wasn't wearing it. He didn't care about his mask in your presence.
"Besides, if you became a chef, I think Mikey would be interested."
"Well, you could cook dorayaki for him and he would be very happy.
Sanzu just smiled briefly. He was very stressed because he had to tell you his feelings tonight. You, on the other hand, were happily eating your dinner, unaware of everything.
After you finished eating, you cleaned the dishes together. No matter what you did, there was always laughter and jokes between you. The first chance you got, you sat down on the couch and started chatting.
"Did you do the same thing today?"
"Yeah, I bought him some dorayaki again, stalked him etc. same things."
"Soooo? did you learn anything new?"
"Hooow?? We've been trying for months but we haven't learned anything new!"
Sanzu was tired of talking only about Mikey every time he met you. Perhaps for the first time, he was bored by something about Mikey. His eyes were drifting to your lips. His attention was completely lost.
"Umm... I don't know... Maybe we're trying the wrong ways."
"Wrong ways? Then I should start thinking of new things."
“Maybe we should try somewhere other than his house!”
Every time Sanzu opened his mouth to speak, you wouldn’t notice him and would interrupt him. He was getting more and more stressed. He wasn’t good with words anyway, and your constant interruptions were stressing him out even more.
“There’s a cafe he goes to all the time, should we try that-”
This time your words were cut off.
Finally, he couldn't resist and kissed you. While your eyes widened, he squeezed his own shut.
His lips stayed on yours for a while, he couldn't even breathe. His grip on your chin was tight. As if he wanted to express all his feelings with this kiss.
Finally, he pulled back, and you were both out of breath. Sanzu's face was bright red. He wasn't used to things like this.
"Wha- What was that just now?!"
"I.. tried to speak but you cut me off. I couldn't stand it.."
Sanzu couldn't look you in the eyes, and you were still in shock.
"What? Why would that be a reason to kiss?!"
Sanzu raised an eyebrow at your reaction; this was definitely not the reaction he was expecting. After all, he thought you were in love with him. Finally, he spoke with a confused expression as he looked into your eyes.
“I’m.. in love with you?”
Yes, you were surprised by the kiss, but this was something you never expected. This boy, who you had been shipping Mikey with for months, was in love with you. You thought he was joking.
“You fucking serious right now?”
Sanzu's eyebrows finally furrowed, both stressed and still confused.
"Of course I'm serious! I've been in love with you for months!"
You both froze. Sanzu blinked for a few times, he never expected something like this.
"What the fuck?! I'm not gay or anything! Where did you get that from?"
"I was shipping you and Mikey, I thought you liked him or something!"
He froze when he heard this, but a few seconds later he burst out laughing. He had never imagined that this was why you'd been helping him for months.
"I'm not in love with Mikey or anything, I'm in love with you."
You still couldn't accept that he was in love with you. You never tried to look good next to him, you were always in your natural state, and... he was in love with you?!
Sanzu's expression started to fall for a moment as he looked at you.
"And... I thought you liked me. I'm sorry I kissed you-"
"No no wait! I didn't say I didn't love you- I mean, okay, I didn't say I did either, but that doesn't mean I'm going to reject you!"
Sanzu's eyes widened, he was getting very excited. He leaned his head forward a little and moved closer to you.
"So.. will you be with me??"
It was so sweet to see his excited and eager expression, a smile appearing on his face. You leaned forward and kissed one of the scars on the corner of his mouth.
“Yes, I will be with you.”
Sanzu froze when you kissed one of his biggest insecurities, but then he smiled. Mikey wasn't on her mind, only you.
"Then you're mine from now on. But I don't want any more 'Mikey stalking dates'. Let's go on normal lovers dates."
He said with a teasing smile on his face as he leaned in and kissed your lips again at the end of his words.
