Biscuit Teacher and Star Candy (2005)

Both stories are older woman / younger man romances.
In Biscuit Teacher Star Candy it's a student / teacher relationship and in Ruk Sutrit it's a teachers assistant and a boy she tutors who fall in love. Also in both the male lead starts out as immature rich brat only to grow and change because of the female lead.

Both shows are noona love stories. OML is about a super star who learns to be a better man as he leans to love and take care of his child. BT&SC is about a neglected and rebellious high schooler becoming a better man thanks to his love for his teacher.

Same female teacher and younger male student. While chugakusei nikki is more melodramatic, biscuit teacher and star candy is more funny.

1. Both are older woman and younger man love.
2. Gong Yoo
3. Gong Hyo Jin

Even though this one is a little slow and if you like age difference kdrama and Gong Yoo you can watch this. He is too cute!

Female teacher and younger and male student dynamic. They are reeeally cute and funny together! Suuper cute watch the puppy love the male leads have fot their teachers, and how they fall in love.

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 dramas are about the Student-Teacher relationships with the teacher being a few years older to a graduating high school student.

Similarities:
- male student / female teacher relationship
- in both dramas we're dealing with bickering couples
- ML is spoiled but kindhearted, he becomes a better person because of MF
- MF is kind, helpful and tough, she doesn't give up easily
