Chugakusei Nikki (2018)

Nevertheless, an incident leads to Narita Misao developing feelings for him. Ichikawa Kazuya also becomes attracted to her. The couple soon enter into an intimate relationship, but Narita Misao learns afterwards that Ichikawa Kazuya is engaged to his girlfriend.

Both dramas have obsessive male leads who are withdrawn and angsty. The only bright spot in their lives is the female lead. They're both very protective of her. In both dramas their whole lives & every decision they make revolves around her.

The Ml is high schooler 17 and Fl is 27
Both Male leads are nice
The Female lead is not teacher but in some way is as he fixes the rich brat kid Male lead.
The second Male lead is very capable.

The stories aren't similar, but the filming techniques are alike and both have the same type of feeling.

Both are teacher-student romances with a gloomy, somber tone, complex, well-written characters, and strong performances.

"Rikon Doukyo" centers around husband Konaka Masaru and wife Ichinose Naoko who seem to have a happy family life. All this comes to a seemingly abrupt end when the couple decides to divorce. Yet, the couple soon finds themselves living together again even though they are no longer married ...

This is Korean vesion of this drama.
Not ocmpletely the same storyline but both reveals a relationship between a minor and a teacher.

If you enjoy Student x Teacher romance you might enjoy these. However, HajiKoi takes an approach more to comedy while Chugakusei Nikki focuses on melodrama.

Now, before I start, I do want to say that they are completely different stories. Saikou no Rikon focuses on the aftermath of a divorce and Chugakusei Nikki is about a teacher-student relationship over time.

The similarities I found with them is that they both made me so frustrated to the point I wanted to throw myself out a window. With both dramas, the love in the love triangle is so strong that you don't know who's going to get picked or what's going to happen. It leaves you with so much suspense.

They also both have characters (in my opinion) that you can't help but hate because they end up speaking the awful truth (Haraguchi Ritsu (CN) and Uehara Akari (SNR)). They are also technically "the other woman" so their presence may be irritating at times.

Similar age gaps but the stories are different with one being innocent and pure while the other is more sexual and introspective.

what else to say lol one revesed of the other
i love both female cast they are awesome
CloseRangeLove is a movie tho and its more about sweet/cute moments

Remind me of Kobayashi Katsuya, Sato Yuki & Nishihara Aki drama Shiro to Kuro....& still 1 of my favorite drama....If you like this genre this is a must watch drama/movie. Sato Yuki always adorable since Kamen Kabuto days.

Both are about a boy falling for his teacher...............................................................................................................................
