I KNOW HE DID NOT JUST BLUSH..
he first blushed after jihoon asked "how much time have you even spent with him (wonjae) so far? even then, you only met because of my body" so I'd say youngmin was flustered about this misunderstanding and how there's actually a lot more between him and wonjae. so idk I wanna believe that the scene at the end was a continuation of that ( ̄へ ̄)
i normally don’t read manga style stories as i prefer webtoons over them, and i prefer not CRYING MY EYES OUT EVERY TIME!!!! this was such a beautiful story.. i need a live adaptation immediately.. start the casting calls
