you get sent to Rengoku's house,because of the wedding/forced marriage, but the only problem is Rengoku hates you, but his little brother,Senjuro likes to play with you, Rengoku's Father,Shinjuro is cool with you being here.

One Day you walked into Rengoku's room and Rengoku was standing up with his shirt off then he saw you, you were blushing REALLY badly

Rengoku "...what are you doing in my room....." Rengoku says in a calm tone
