OMG YES IT IS AHAHAHA thank you so muchh
I've asked before and still found no luck. The uke has black hair and 2nd ML likes black hair (bi). One time they were playing soccer (I think they're in school), and 2nd ML touched uke's head, and main ML got jealous, he kicked the ball to 2nd ML's face. That's all I remember, thank you (〜￣△￣)〜
