Tbh the whole thing is getting way too long. Like I got u xinlu, but life is life, so Go AwAy, deal with heartbreak on ur own. And rn I think ML reassured his brother that he also cares abt him and thinks abt him a lot, and they will always reunite one way or another, so they are always connected through brotherly love.
The thing is that both Tae and Jae are connected with each other ( which was represented by a red string) this connection is what makes Jae so lucky, without that luck that his brother Tae gave him he won't survive bcz his body is so weak to the point where his survival up to this is a miracle, so basically Jae survived thanks to Tae and both him and his uncle head this fact from him until he discovered it, there's still more clue about their special bond in diaphonic Symphonia later on

Can someone tell me what this last 5 chapters are about...
The brother are connected? The luck? Faith?
