I understand why people like this. It is easy to recommend for those who like forced cohabitation/school romcoms with bits of fantasy.

I enjoyed nearly all of the various relationships and interactions in this series (the friends, the two sets of siblings, the secondary and tertiary OTPs). I liked the production as a whole (the colors are nice, the animations are funny) and didn't mind the paper-thin fantasy. Our leads Jang Ki Yong (as Shin Woo Yeon) and Lee Hyeri (as Lee Dam) also make one good-looking pair.

However, as the show progressed, the main OTP (and their issues) bored me. So much so that somewhere from the middle of the drama until the end I was fast-forwarding most of their angsty/contemplative/sugary moments and just wanted to see everyone else instead.

I'm sure a lot of people loved their swoony moments the way the writer intended them to be. But it just didn't work for me. Woo Yeon was written way too calm, passive, and dull for my tastes. He ruminated by his window too much and he kept Dam in the dark a lot of times. I only looked forward to his moments with our ditzy ex-gumiho Hye Sun (played by Kang Han Na) because he comes alive every time with their petty arguments.

As for Lee Hyeri herself, I liked her in the little bit I've seen her in the reality shows before (We Got Married bits and House on Wheels premiere). Her brand of comedy here is rarely seen in dramaland nowadays. She reminds me a bit of the (slightly) embarrassing FLs in older kdramas like Lee Da Hae in My Girl and Kim Sun Ah. I liked her here but I hope she chooses more diverse projects after this so she won't be typecast.

Anyway, all the supporting characters and their story arcs were fun and interesting so I'll probably rewatch this for them. I'll just be fast-forwarding through the scenes of the OTP.
