Dunno about Mike but Ester is his female friend that we see in the first chapter of season 2. She's the one who tells him to stop using the apps because it's dangerous.
mike is esther's brother. he's tall, white, reddish haired and may or may not be a Love Rival at some point (or thats what the koreans are Theorizing will be his role in the future lol.)
thank you so much(づ￣ ³￣)づ
it’ll be fun if he’s a love rival, spice things up to make taehwan jealousss
hehe u and the bomtoon commenters are of the same mind. lots of jokes about mike being a "Side Man" (u know love rival, romantic spoiler, secondary male love interest etc) and vervent wishes to see Taehwan get jealous and possessive. and i mean if he gets like that over his own brother imagine how intense it can be with a lover ohohoho
Possessive a Taewhan is going to kill me
ok so who's mike and esther that I've been seeing on the spoilers(not the aot ones)?
