Looking for a yaoi manga

Uke was left in the hands of the seme to be looked after.
Seme is possibly bar owner or host and has connections to yakuza.
Not so sure but possibly
Uke family may have abused or sold him, or his family was in some sort of trouble and had debts or died?. Uke may have some trauma
Uke fallen in love but seme may think it is because he helped looked after him
