Supernatural

Shounen ai - seme is a hottie and uke is cute - (spoilers warning) The uke bumps into the seme's items, a bracelet attaches around his wrist, uke can see ghosts after this but it seems like in childhood he could also see them, and he knew the seme from childhood
I'm already in love and its the first chapter - I definitely recommend.

Shounen ai
The uke is a nine tailed fox, in the past life something happened with the two seme's.
In the modern time, uke comes out from an orb one of the seme's finds in a box
Uke is violent and attacks the seme's since they did something to him in the past.
It's interesting and quite cute

I really love this, the uke is a demon, very beautiful per say and the seme is handsome, he has long hair - there's a misunderstanding between the two, the seme thinks the uke tried to drug him on someone's orders - there is also demon hunters
