Damn it’s kinda the same as another manwha except it’s a father and a son

What's the name of the manwha?

I forgot

I think you were talking about Bastard right ??

No. All I remember is the ending about him having an illusion where he was happy with his two friends but then brought back through reality where he will forever be stuck in being a good son. A studious student I think

Is it “Efforts Never Betray”?

Yeah that one!
