Anyone can help me this manga?

I'm searching for this manga I read before. It's shounen ai and yakuza. I think the uke was brought to the rich familiy's/yakuza's house and the family of the uke and seme knows each other. I don't remember much aside from that and I think the characters were still students. Oh and also if I remembered correctly the uke tried to escape the house but the house has super high walls surrounding it
