I will pray that you don't have to wait that long.
HT ChaChaCha is a real nice slice of life drama. Doesn't take itself too seriously. Has a catchy OST. I was humming the OST all last long labor day weekend. If I had to describe HT Cha Cha Cha, I'd say it is "Crash Landing On You" meets "Reply 1988". And those two dramas are my most favorite K-dramas.
