Underfell monsters are crushing on someone and it seems to be mutual, but then another person pulls the monster aside and tells the monster to not try to flirt with said crush because, "Them and I are already a thing." However, this person is just delusional and decided that the crush being polite meant they were dating. The crush is livid and verbally tears the person a new one when this comes to light and lets it slip during the tirade that the monster's crush is indeed reciprocated.
Soft Edge isn’t really much of a flirt, he’s more likely to just be slightly nervous and flustered in your presence. Genuine compliments, that are just soft and endearing are more his thing. So when the person pulls him aside, he’s very surprised. He’s... not flirting??? But he’s kind of crestfallen at hearing that from this person. But then he brings it up with you, saying he didn’t realize you were dating someone already. You stop and ask for details, and he tells you what just happened. You correct him that you’re not dating, and when you say that you in fact, like him, he’s absolutely DELIGHTED. His chest is puffed up, and his head just seems to be held a little higher, as he’s simply full of pride because you like him back. Once this person has been shooed away, he’s asking you on a date.
Oh he’s so MAD about being pulled aside. Was this really necessary??? What kind of douchebag do you gotta be to do this sort of thing??? “You’re S/O is a douchebag.” He says when he comes back to you. You pause blinking like the blond man meme. Pardon???? He looks confused now. “Ya know, them over there??” he gestures to the person. You tell him you’re not seeing anyone, and you look PISSED. Oh, OH SHIT. You march over, and give that fucker a piece of your mind. Red Boy is hyping you up the whole time, thinking this is absolutely FANTASTIC. But he’s stunned when you say that you like him and he’s just tugging at your sleeve. “Ya,, Ya like me?” He’s asking with hope in his eyelights. OF COURSE YOU DO. HE’S DELIGHTFUL. He’s grinning at ya and kisses your cheek. “Cool, like ya back.” He glances to the person. “Take a hint, Scram.”
Big time flirting with you, and then he gets interrupted by the person. Um. Hm. For some reason this doesn’t sit right with him. It’s written all over his face, the confusion when he comes back and you ask him about it.
“Are, are you dating someone?” You answer no. HM. SURE SOUNDS. SUSPICIOUS. PERSON. He tells you why he asked, the person pulling him aside. You fucking LOSE IT. How DARE they???? When you say that you like Jerkby when you’re chewing the person out??? He’s pleasantly surprised. Holy shit its reciprocated. hOLY SHIT. He kicks the person out of his bar, and asks you out on a date and makes plans. I mean, you like each other. You might as well right?
He’s just softer around people he likes, kinder, and when the person pulls him aside. He doesn’t believe it, simply because of the possessive behavior. “Funny, they never mentioned that. I’ll have to ask them.” He tells them before simply striding over to you. He asks you and tells you that they’re saying you’re a “thing” and you’re absolutely PISSED. You chew them out, and accidentally let that info slip of liking Grump. He’s smirking, He’s very happy to hear about this.
“Well, should we go on a date and leave them behind??” He asks you, interrupting you chewing this person out. He leaves with you, and his aura simply has the SMUGGEST aura.
