Tooru [BL]

Being with Oikawa was really strange. You might wonder why? Well, he's always flirting with girls, so he must be 100% straight, but no. Wrong idea. Oikawa doesn't really know what he is. He flirts with girls, but at the same time, he has a boyfriend he's attracted to, and he's a guy—I mean, guy with guy. Why would Oikawa be with another guy? Probably because he's playing around with this guy, but Oikawa really does have feelings for his boyfriend. It's not just for fun; it's because he loves him so much, but he can't help flirting with girls too.

Sometimes, Oikawa doesn't care about his boyfriend Loki's feelings for him, but at the same time, he does care about his boyfriend's feelings. He can sometimes be selfish with Loki, wanting only Oikawa to be the center of Loki's attention, but at the same time, he wants his boyfriend to be happy.
Sometimes she doesn't care about breaking her boyfriend's heart and will continue flirting with other girls, even though he doesn't yet know that every action has a reaction.
