Yea, l get where Seungtae is coming from. I mean he was motivated solely by his goal to avenge his parents and that makes it easier for him to tune out anything (including his feelings) that has little to do with his said goal . So him being cruel to Sihyeon is justified, kinda. (Oh don't get me wrong, l don't condone it. I was just imagining being in his shoes). But now that everything is out in the open and his suspicion over Sihyeon's behavior has also proven wrong, he probably felt comfortable acknowledging his feelings towards Sihyeon.Good , great even. But this 360° turn on his part is a bit too much for me. It's a complete turn off, I must say. Let him still be an arrogant stoic asshole who fight his inner demons day in and day out so that he won't blindsided both Sihyeon and the readers. This pathetic sad puppy act confused the heck out of everyone and it's unbecoming of him.

Stress is hitting them hard. Now they are not as pretty as before(esp Seungtae lol).
