Hello there Anon! This is a very sweet request and I’m more than happy to fill it for you!
*Kaminari would have had a crush on them since the beginning of the year. The first thing he noticed was they’re looks and boy did he find them attractive. After a few days, he saw what a cool person they were and his crush was solidified.
*Even though he’s not the best in the class, Kaminari is extremely confident. As soon as he felt ready, he didn’t hesitate to walk over to their desk and ask them out to dinner.
*Sure, most people see him as a sort of pig, but he is actually a real romantic. Kaminari would take them out on little dates until they both got to know one another, then he would finally ask them to be his partner.
*Kaminari is pretty big on PDA but would respect his S/O if they were uncomfortable. His favorite thing is hand-holding but he also really likes kissing hello/goodbye.
*He is a huge cuddler and they would spend most of their alone time holding onto one another. Even if they are studying, he will be laying in their lap. Physical contact is a huge thing for Kaminari.
*Kaminari is the PROUDEST boyfriend. He would talk about them non stop and he would be their number one fan!
*Tamaki would have had a crush on them since childhood. One moment they were just friends and the next he had major feelings for them. He would keep it to himself to make sure he didn’t ruin their friendship.
*Everyone would tell him to ask them out, but he would always refuse. The few people who knew about his feelings understood that their friendship meant more to him than the possibility of a relationship.
*When they pulled him aside and asked him to the movies, he initially thought they meant as friends…until they made it clear that it was a date. Tamaki agreed of course, but that didn’t mean his anxiety wasn’t through the roof.
*After a few dates, Tamaki began to relax into his normal self around them. Everything was going really well. In fact, Tamaki kissed them first. Being in a relationship with them felt so normal. Like they were always meant to be together.
*Tamaki is not big on PDA but doesn’t mind a quick peck goodbye. He isn’t one for hand holding (too many people stair) and likes to keep most of those things in private.
*Even when they are alone, Tamaki gets nervous about doing intimate things. It’s not that he doesn’t WANT to, its that he doesn’t know HOW. That being said, he will follow their lead and do what they are comfortable with.
*Tamaki is a very kind and empathetic boyfriend. He will encourage them to do what they want to but also understand when life gets too hard.
*Sero would spy them sitting alone in the dining hall and walk over to befriend them. He would get to know them and become pretty close, when one day he looks at them and realizes, “damn they’re hot!” Sero might begin to act a bit sheepish around them once he realizes his feelings.
*After a lot of build up from his friends he would finally have the courage to ask them on a date. He fumbles through his words and the two of them end up laughing together by the time he finishes. Much to his relief, they say yes!
*Sero will take them to a few movies and a walk in the park or two, but he’s not the best at romance. They don’t seem to mind of course, and they enjoy the effort and the chance to get to know him on a different level.
*Sero can’t help but kiss them and hold them even when other people are around. They even have to tell him to cool it a few times when teachers have been around. Sero once got them both detention for making out in the halls between classes.
*When the two of them are alone, Sero is a huge sap. He will cuddle and tell them how amazing they are. He is HUGE on words of affirmation. He would always want to be around them and will never hesitate to tell them how much he loves them.
*Sero is the fun boyfriend. He’s mischievous and may steer them in the wrong direction once or twice, but its all in good fun. He will make big obnoxious signs for them as a form of “encouragement” and will always give them congratulatory kisses.
