Hajimete Koi wo Shita Hi ni Yomu Hanashi (2019)

Older woman/younger man relationship between a working woman and a student. HKWS is much more of a taboo relationship since the boy in not only in high school, but is actually her student at cram school, but the FL acknowledges keeps her distance (or tries to), so it feels cute rather than creepy like some other teacher/student series.

Both dramas have the same theme, additional lessons from tutors to enter prestigious schools / colleges.

The main character in both dramas also has the same profession, a tutor.

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.

An age difference of about 10 years. The ML falls for the FL first and a lot of the relationship conflict is internal and about the age difference. She's also pursued by other men more similar to her age. She has limited dating experience too.

Both series are about women (who are quite oblivious most of the time) learning how to gain their confidence. They both also feature cute romances where the male lead helps her come into herself.

Junko Harumi was once a model student during her middle school and high school days. However, she, unfortunately, failed to enter the prestigious Tokyo University, and her life has not gone smoothly since then. Now, at the age of 31, she works as a teacher in a private tutoring institute, hoping to help other high school students succeed where she has failed in getting into their university of choice.

She was not having much success until one day, a high schooler with bright pink hair and his father enter the institute. The father believes his son is a delinquent and wants the institute to help him enter a good university. Junko decides to take on the challenge. Will she be able to succeed, and will she be able to also finally have a romance when 2 other men appear in her life?
