90's nostalgia (taiwan and thailand)
protagonist carries a walkman around
searching for the truth regarding their deaths

It's the same drama just one was made in 2001 and the other is a remake in 2015. Andrew in the 2001 version is so AMAZING highly recommend!

Slow burn mysteries in which the character our mc is attracted to disappears. The endings are both open and leave room for own interpretation.

Both are crime, detective, and undercover police work.
In both of them ,both lives are somewhat destroyed by a specific drug task force. They both lose someone dear to them. Like in this one he loses his fiancee, so he wouldn't put her in danger. But she's still intended to look for him and make him turn over a leaf, not realizing he's an undercover cop.

Look forward to this drama.
Both are in the gaming world, and in this one she catches the elite game leaders attention, but she's made a vow not to have any romantic feelings for someone in the same field as her. After much effort what will become of her vow? Can she avoid romantic entanglement?

Both have the concept of the frugal FL teaching her way of life to the ML after the ML lands in trouble for his way of spending money

-Both of them have a groups of friends and rivals that help to learn and motivate from each other.
- Both ML is strong and lovable

I'm connecting it to the story in general. there was a scene in Honey and Clover where the male lead leaves everything behind and gets on his bike with no destination, and in Nagi no Oitoma the female lead also does that. both also had that same drive, they wanted to get away from their lives and start fresh even for a little while

I'm recommending the korean vr becasue that's all I saw. but both are about a female character who leaves her life behind and take a break to heal their souls.

SaifahZon Story is originated from Why R U the Series. The characters of Saifah and Zon were already in that series and their love story began in Why R U the Series. Anyone who finds SaifahZon Story but never watched Why R U should watch Why R U first to better understand their love journey.

both have weird teacher that somehow transform the dynamic of the class and the students. Taiyou to Umi is more realistic than Gachi Baka!

It have similar story (ex-delinquent turned teacher) and the teacher help the students to become better. GTO is a bit darker than Gachi Baka!

The usual teacher with unlikely background and reform the delinquents. the difference is that Gokusen feature a female lead and all-boys school.

This is the first season my luvs:))
You can watch it if you want to understand the whole thing hehe, I watched season 2 first and got confused as hell lol

The scene from Close Range Love, where Yamapi, the teacher has his female student under the desk and then he is infront of the class, then he purposely drops his pen to be able to crouch under the desk too and kiss this female student under the table, this scene also happens on the drama Be With You...so I feel that these two, the J movie and this C Drama are similar...not so sure about the story but I think on a vague discussion, they could be similar in plot...
