please someone tell me that the seme isn't asshole. i just want someone to be gentle with him

No, I'm not mistaking them.
The seme treats the MC like shit (the party scene with the vibrator? WHY? He didn't need to do that, for example) and takes advantage of him, he makes the MC think that he is doing him in favor when seme is the one that has more to gain from their bargain.
So, yeah, he is an asshole.

The seme is a major asshole alright.
I am a little confuse, isn't the seme suppose to help the uke to be safe from the brother? There were a few chapters at the end that he wasn't mentioned at all, and tens years later, and at the very last scene the seme appear again and Yigon ask him for the same favor years ago?????
MY HOLY FAVORITE MANGA IS FINALLY BACK
