Bro fuck Saki your brother was already like this way before Tsuyoshi showed up and if he asked to leave I bet he'd let him with all his fingers remaining. But your gonna be this cordial with the guy who is involved in your kidnapping?
I can't even blame him, bro has been treated like an object by 4 different countries including his own and has already been marked and can't live a normal life anyway. You blackpilled him and surprised he's crashing out.
