This morning, somebody put a present in Yui's shoe locker.Ah, that's right, it's Yui-senpai's birthday today, isn't it?And there was a love letter attached to that present!Eh?Even though this is a girls-only high school.I guess Yui has some female fans around, too?Aww, shucks.... That's strange. I'm sure I put her present in her shoe locker...But I didn't write any love letter...
