You were more than convinced when Todoroki and Deku kissed you silly right behind Bakugo. Honestly, you didn't expect them to be such great kissers but, at the same time, they had plenty of time to practice with each other. You would never see one without the other and, well now you were a part of that. You were scared of what other people would think because not everyone is so open to established throuples let alone four people in a relationship. It was a lot of communication that needed to happen and, that usually happened when the four of you were together alone which you appreciated. You listened to the established rules and you talked about them. 

"The main rule we have is to not lie to each other. It's hard, it's easier to just keep secrets or to try and figure it out for ourselves." They all gave each other glances at that. It seemed all three of them had issues with that but, they were willing to work out any kind of kinks with each other and now you. "Sometimes it's best to talk it out and see if we can all come up with a solution to the problem." That was Izuku who was talking. They all refused to answer you unless you called them by their first name which you did a little uncomfortably but, you knew you were going to get used to it. 

"Another rule we have is giving each other space, being able to read each other's moods. It's a lot of work and we all make mistakes but, we are working on it. We are young but, this relationship is worth it. I...want it to work with not only them but, with you too Y/N." You really appreciated how much effort they were putting into making sure the relationship worked around you as well. You were a new person but, you didn't feel bad because this must have been how Shoto feels and still at times feels. Bakugo and Izuku knew each other growing up even if they didn't have the best of relationships they still knew each other for much longer. You can sympathize with Shoto in that department. 

"I still can't believe I am this lucky and I am actually a part of this relationship. I will do anything to make sure it works. Obviously, I am not perfect and I will make mistakes. I just want you guys to point out any kind of mistakes or misunderstandings that may or may not occur. I will give you guys the same courtesy as well for me. This relationship needs to work and I want to put in all the effort to make sure it does." The four of you talked some more and beyond heavy petting and makeouts nothing serious happened which made you feel so much better. You weren't prepared for that level of intimacy yet. You wanted to understand their quirks, their habits both good, bad and in between. You wanted to see them at their perpetual worse and the same for you. At least that's the plan but, sometimes emotions and feelings get in the way and control you more. You'll try your best to be as prepared as possible. 

"I don't care what any of the extra's think of us, they can fight me and die if they got something bad to say." He let off a couple of pops in his hands which you rolled your eyes at fondly. He was such a feral gremlin. "However, I do understand if like...you're not ready for that. We won't hide it nor deny it if anyone asks about our relationship." At least he was honest and you thought about it. You weren't ashamed of them, they were more than likely going to be the next big three and that was something you wanted to help with and be behind with. You really cared for them as people and you knew you would grow to be deeply in love with them for however long you four plan on being together. 

"We can tell people. I am not ashamed of any of you. You three are the strongest in our class and more than likely the next big three so that's less of a reason to be ashamed. I just want to support you guys and see all of you make it to the top while working on myself and our relationship. It will be a lot of work with tribulations and hard spots but, I truly believe that you guys are worth it." It was a bit of a mouthful and judging by the heavy silence you looked up to see they were staring at you with various looks of awe before Izuku grabbed you in a hug. You adored him and his freckles. You hugged him back and soon enough you felt an arm around your neck pulling you into a side-hug. You looked to see Bakugo had turned his face to bite your cheek. 

"We will support you as well even if you won't be number one. That's going to be my spot." That's when the playful arguing ensured and you rolled your eyes at their antics. Everything was going to be okay and you didn't regret anything. You were embarrassed that they found out through a mirror but, at the same time, you were happy they saw all your drawings. Who knew how long you would have pined after them and just not have said anything? Possibly a very long time and more than likely after graduation as well. 

"You want to study together in my room with us? It's quite spacious and I got soft chairs we can sit on or we can just sit on my bed." As you guys looked at Shoto that despite being so monotone seemed to be a little nervous about you declining but, you wouldn't do that to him. 

"Of course, I would love to study with you guys. That's one way to kill two birds with one stone." He bit his lip a little confused with your saying "What I mean is that I get to spend time with you guys as well as get some necessary studying done. You knew Aizawa-Sensei would have our heads if any of us would fall behind." He seemed to perk up with a slight twinkle in his eye as the four of you continued talking, standing close to each other and making your way to Shoto's room. You really were lucky.
