I believe I've started this before but gave up in the first episode. Probably because of the ML being yet another wealthy, handsome manchild.
This time I hung on in there for just a little longer and whilst I did still find him infuriating at times his (eventual) character growth and the story were ultimately rewarding.
This isn't ground-breaking stuff but it is a good, wholesome weep fest.

The performances are pretty good though characters don't all have a lot of depth. The FL probably gets the prize from me.

The bromance and sismance are engaging and emotionally rewarding.
The only real flaw for me was the Baek Seol story line. The In-Laws were a bit too overdone and I found her acting unconvincing. The rather obvious duck lip probably didn't help. I didn't really feel her motorbike friendship came over as innocent either which rather spoilt it and the ensuing story line.

I have to admit to skipping through some of the longer emotionally manipulative moments.

Story: Good but not standout
Acting: Good with alright chemistry between many of the characters.
Music: Ok didn't really grab me but not mute button awful
Rewatch: Probably not - I enjoyed it but not to that great a degree.
