"But since you are another member of the clan, you are another obstacle for me and my brother!.." With a sharp insight into what was happening in Rin’s head, a realization came to you too: it will be very bad for you.

Rin is the kind of person who won't leave you alone if you bother him somehow. If you need to be removed from the path to his goal, why he shouldn't do this? He's strong enough to overpower you. It will be easy for him to get rid of someone like you.

"...My brother won't even like you, you're such a useless fool!..~"

But still... The chance of persuading him or defeating him is small, but not zero.
