Rui and Tsukasa were your boyfriends! Despite them being quite weird, you still loved them. One day, you were hanging out at Rui's house while he was working on some stuff for the next show in his room. You had gotten quite tired and Rui noticed, so he stopped what he was doing so you two could cuddle. In the middle of your cuddling, just as you were about to fall asleep, the door opened and in walked Tsukasa.
Tsukasa: "Cuddling without me?" He pretended to be offended, but he obviously wasn't. You just snuggled into Rui more, trying to block out Tsukasa's loud voice.
Rui: "Fufu~ How about you join us?" Rui patted the spot next to him to invite him over, but Tsukasa sat next to you instead. He wrapped his arms around you and kissed the top of your head and Rui giggled at your flustered expression.
