Worse? He's no saint but he's done a lot less harm to Nakyum jesus_christ
Nakyum had chances to run away from seungho more than once but In-hyun was the whole reason why nakyum stayed until now and endured all of that torture, and now he’s staying because he thinks seungho loves him, although that doesn’t change that he stayed until now because of In-hyun.
Does his noona really not know that in-hyun is worse? That shitty bag of a person ( ̄へ ̄)
