It's his niece. Post credits show a character called Woo Cheong Ah. The name of the one Chae Woon is talking to on his SNS is Cheong Ah. Since in KR, wives keep their family names, Woo Cheong Ah and Woo Chae Woon, we can conclude, are likely to be siblings. I got the info from this post: https://twitter.com/jjh_s_01/status/1779053628520816907

I read somewhere as well that the sister's husband is irresponsible so Chae Woon is the one supporting his niece's education.

Huh? We are not defending Disney, we are trashing your cheap statement. Lol.
Why the need to post your sh*tty opinion anyway? For clout? For validation? Because, honestly, that is what's really pathetic. Have some manners and don't sh*t on public, will you pretty please? lmao

This is why we need to rate dramas honestly not just because we like the leads. If we give crappy dramas a high rating just because of the actors, the directors and writers wont work hard anymore and just cast popular actors/celebrities. The celebrities we like eventually suffer the consequences when they end up on "unsalvageable" dramas.

I find him attractive. If you find frail-looking girly boys attractive, for example, then that's your thing. We ain't gonna throw around "they're unattractive I cannot stand them" statements as if it's the standard.

In the last scene of the episode 4 teaser, Saki appears to be crying. A saw photo of Koichi handing her (in the same clothes as that last scene) a brown envelope. In the next episode, Koichi will likely initiate the divorce and ask Saki to reconcile with the ex-boyfriend.
