I think so too. I don't think Seungho would kill him, because of their history together, so he will probably kill himself.
The set up for Jihwa and the hobo assassin is so clear, the author wouldn't create a fan service type of character like the Tarzan and parade him shirtless in preparation to swing dick on Jihwa if it was not the whole purpose of the character.
Meaning: Jihwa will get his side piece and because happy endings can't be given to bad people, he will get his mini redemption trope arch too.
The most probably death in this story is Min, he is kept kind of ugly, no sob story and no one likes him.
i think jihwa is going to kill himself. i really want it like that lol. cause it makes sense yk
