Do you guys know a story where uke was talking with seme in the phone but they didn't know each other yet. Seme work where he will receive/call other people to soothe someone feelings or something(i don't really remember i read it last year). Then one day uke can't contact seme anymore (he loves seme already). I hooe you can help me. Thank you
