Everything was always very complicated between them. Marinette in love with Adrien and Adrien in love with Ladybug, both unaware of each other's identities and feelings.
Marinette always remained hiding her feelings for Adrien, too embarrassed to say anything and Adrien continued to yearn for Ladybug. This continued for a long time, until your arrival in their lives.
You were a new student and felt out of place after leaving your old school and your friends. You hoped to make friends at this new school, but you were afraid you wouldn't be able to do so. But luckily, or unluckily, you met Marinette first and she introduced you to her friends, who immediately liked you.
Marinette liked you, at first sight, you were so kind and sweet. She almost fell right there and it confused her, but she couldn't help but admire you.
Adrien became interested in you after a few conversations, and you caught his interest and attraction. He had something about you that made him attracted, and curious, an unknown feeling that he wanted to feel more of.
It wasn't difficult to notice their interest in you, Marinette constantly stuttering and blushing when you were around and Adrien, although shy, loved flirting with you and seeing you blush.
It wasn't easy to admit their interest in you, Marinette was still in love with Adrien but she really was in love with you, therefore, she didn't know what to do. Adrien was more resolute and acted in the way he knew how wanting to declare himself because he could no longer keep his feelings to himself.
Adrien was the one who first noticed Marinette's interest in you and he was surprised to notice that he didn't have a problem with it. If it were anyone else, he would have, but not with her. Because Marinette had a habit of stalking you incessantly, it didn't take long for her to realize that Adrien liked you. She was curious and excited, not jealous like she thought she would be.
They talked and decided to act quickly, both confessing to you. You were surprised and flattered and accepted, and finally, a romance happening.
Marinette is very jealous and overprotective, always wanting to know where you are and she will be very worried if she doesn't know. She will go so far as to use her Miraculous to look for you, even knowing the consequences.
Adrien is possessive, getting jealous very easily, and doesn't react well to it. He doesn't like it when you're with someone other than him and Marinette and will use intimidation to make someone stay away from you, whether with money or even his Miraculous.
They have always been very protective of you and at any sign of danger you will be quickly hidden and protected. They already talked about giving you a Miraculous, but Adrien considered it too dangerous. There was always a chance you could get hurt and he wasn't going to allow it.
You are spoiled intensely, clothes made by Marinette and bought by Adrien, jewelry, food, expensive and extravagant gifts to the simplest ones, like roses. You will never lack for anything as long as they are by your side.
They want to see you happy more than anything and will do everything to make that happen. They can't even think about the idea of you being akumatized, the idea alone sends them into a frenzy at the thought of it happening to you. No, they have to be sure that this will never happen.
Marinette is very kind and soft, a mask of her true stalker and extremely jealous side. Adrien is kind and calm, always with a smile on his face and ready to make you smile, but he acts very strangely when you don't do what he asks.
They know they shouldn't use Miraculous for selfish reasons but when it comes to you, they won't care. Marinette doesn't care about ruining herself for you and Adrien has been ruined for a long time.
You are theirs and anyone who tries to get in the way will suffer the consequences. After all, you didn't just belong to Marinette and Adrien, but also to Ladybug and Cat Noir.
