hmm not yet I think
Yep he has.
Which chapter?
Okay so I could be wrong since I keep up with the raw Japanese version and Korean one but ….
Spoiler
I think this chapter is already out - he is the guy that cover his face with shopping bag when the ML and FL go to the shop of ML’s best friends.
He so I’m sorry I double checked and I realised he hadn’t, it was my bad to confuse the raw to English one.
But what I can say is …. He appears in ….., chapter 34
So you meet him in the next update.
Alright thank you for your clarification
