LIKES:
Locations & scenery were pretty.
Colour pallet, cinematography all good.
Wardrobe well chosen.
Cast suited their characters too.
Writing: I enjoyed the friendship/bromance vibes and the two new girls were given just the right amount of screen time.
OST/music for once wasn't annoying.

DISLIKES:
Writing: I felt annoyed by the ML pining for his ex GF, it lasted too long. Also very predictable ending and I feel they left Hwang In Yeop's Gi Jae Yeong the odd one out at the end of the show. The could've concluded his story line better.
Acting: wasn't the greatest (at one point Yoo Dong Guk while wearing the lensless glasses, put his finger through the "glass" to rub his eye (lol).
Production: Shaky Camera Syndrome [they should've used a film stabilizer] and zooming in too close. Camera work was very amateurish.

OVERALL:
I don't need to rewatch it, but it is easy fluff and a quick story. I want to see more of Hwang In Yeop dramas and hope he has more ML roles. I recommend it for those liking friendship dramas that are short and not very developed.
