probably because the ml had a scandel, he's now doing short dramas.
A few years ago, his ex (forgot her name) I think called him out for being controlling and abusive. If u go on the comment section of his page u will see ppl talking abt it. I think someone posted a link there.
Idk, when I saw the drama airing I never knew it was darren so I just skipped past it but when I checked on mdl I just found out it's him and I realised I already commented on here before.
