The last stage is a lot more like "Kakegurui" and less like "12 suicidal children" but it still fits that type of feeling.

Sexy Fls
older woman
fashionable leads
the closet in room 13 is like the vampire's room( lol)
both fls have drinking problems

Heavy on the bromance and just so good and melodramatic. The chemistry between the leads is excellent

Both beautiful films about people who have their own moral code and the gritty reality of their existence. Both are just perfect in my opinion.

Both films are about criminals and gray characters with heavy bromance but Zebra is extremely dark and violent, downright off putting in its violence (which I LOVED lol) and Wilderness is somewhat tamer.

Again, the relationships between the characters is similar and both deliver the same punch of gritty darkness though Grasshopper can be a little more violent and gory.

I kept thinking about Double Mints when I was watching this. The same brilliantly executed desperation and melodrama that's the beauty of both films while being intense and jarringly violent. The relationship Shinji (Suda Masaki) has with Barikan (Yang Ik Jun) or with his ex gangster boss had the same undertones of Fuchikami Yasushi and Tanaka Shunsuke's relationships in Double Mints.

Both have male leads who don't want to get involved with the female lead in the beginning but are curious about her. In both dramas, the female lead keeps on getting into trouble but both are smart and strong, but she ends up dragging the male lead around with her.
I watched Who Are You? soon after Catch The Ghost had started airing and to be honest both have similar mystery and comedic vibes. But I feel the chemistry between the leads in Catch The Ghost is much better since its a tagged romance drama which is not in case of Who Are You?
Anyhow, if u like Catch the Ghost , I recommend Who Are You?

Subtle conflict, Beautiful cinematography make romantic feeling throughout watching the movie, day to day couple conflict, like watching couple in real life, character growth
