About u: ur shinobu, ur 15 ur friendly, teasing, beautiful, cute, small, nice, ur bf is giyuu (leave if you don’t like the ship) he’s 18, last Highschool year (you two go on same school) he likes you is a bit overprotective, he’s cold and emotionless but really cares about you.

But the thing is: ur on your period, and he doesn’t know yet, u have mood swings, cramps, body-swings and other period symptoms… That’s all
