I really want to tag this story, but...

I forgot.. Its about the uke despite from being cute and small, he has great physical strength. He even broke a boomstick. He pretended to be weak and frail in front of seme coz seme saved him from being bullied everytime. seme and uke are not from the same school. seme wears a black school uniform. When the seme knows and confronted about the truth, uke collapse from a fever...It's a oneshot inside another story.. thats why until now i can't find it.. T_T.. Heeeelp~~~~
