Sharon Ong

The casting was a bit off for the lead's daughter I-na. She's literally a small child and doesn't fit well with her classmates who all looked several years older than her. It was weird when the older looking boy had a crush on her as she looks like his little sister lol

One of the funniest K-dramas I've watched! The lead actor really suits this role, his eyes are hilarious and all his expressions too, watch the show if you are looking for laughs!
