Tbf, I really became aware of HJM in Love Scout even though I already enjoyed her in The Light in Your Eyes (then again, the true female star in that is Kim Hye Ja).

YMMV re: One Spring Night, but I just enjoy it as a breath of fresh air after so many flashy, dramatic K-romances. People work ordinary jobs and talk about things (even if conflicts take time to be resolved), and no endless, dramatic rich guy tantrums. Plus, I really, really like the ML here. Didn't get the Jung Hae In appeal before (even while watching Love Next Door where I found him cute) but this totally hits the spot for me!
