Di Jiu Jie Ke (2022)

The story idea is almost the same, a young man who falls in love with an older woman. In the story "Kenja No Ai" it is told that the woman take care of the guy from childhood, she gives love and attention that is different from what the guy's mom gives, making the guy feel more comfy with her and all of that made the young guy fall in love so he couldn't live away from her, this is where the story starts to get more interesting......

Very very similar and the positive vibe is the same. The FL and ML are absolutely stunning and very good-looking. It is rare to see such a well made J-drama so you should give this one a chance

The plot is the exact same premise, older teacher FL and younger student ML, with disapproving families and a second male lead that's probably doesn't make much of an impact.

both tell stories about the relationship between teacher and student. not just a romantic relationship, but how they started a relationship from just a platonic relationship.

Both dramas are about a love story between a female teacher and a male pupil.
Lesson in Love is a taiwanese drama; Hajimete Koi wo Shita Hi ni Yomu Hanashi is a japanese drama.

In both dramas a female teacher wants to take revenge on a woman who hurt her in the past. His revenge falls on this woman's children: the son in Lesson in Love, the daughter in The Glory.

This depiction of the teacher student relationship in this drama is very similar to Lesson in Love. Main difference ML is not privileged with money and power or he is not a bully.

ML-Falls in love with Teacher. Smart
FL Dedicated to teaching and her students

They connect over their love of math.

The two dramas have many points in common: both are about the relationship between a male student and a female teacher. Their story is troubled due to social pressure.

Both have teacher and student relationship
Probably difference is that here student is student but the one im recommending the student is an adult.

both tell stories about the relationship between teacher and student. not just a romantic relationship, but how they started a relationship from just a platonic relationship

The premise of the teacher student relationship is the same without a real age gap. This drama is more of a comedy as opposed to this heavy weight feeling drama.

both series deal with student-teacher relationships. the female lead is the older one, while the male lead plays the student. both guys have a rebellious streak, but eventually falls for the girl.
