They both have similar plot and themes such as the husband cheating and the wife having a younger man as a love interest.

A love story affair with a bit different storyline & plot with mature sexual content but both is worth watching drama. If you like mature love affairs story I definitely recommend this drama.

Michi, a 26-year-old high school math teacher, tentatively accepts her boyfriend's proposal of marriage, uncertain of her love for him, but feeling pressure from her father and society to do what is expected of her.

Hikaru is a 17-year-old boy frustrated by his home life with his single mother. After being expelled from many high schools for bad behaviour, he enters Michi's class as a new transfer student.

As their relationship grows, they realize they both feel they've lost themselves to the pressures of those around them, and it is this common bond that draws them dangerously close. What follows is a heart-wrenching story of forbidden love where Michi must face society's judgement for corrupting a minor, abandoning her fiance, and disappointing her parents and co-workers.

Both dramas are similar for their cheating aspect, both FL's are not satisfied with the relationship they have with their husband, thus, looking or accidentally looked at another man that appreciates their value more as a woman. They did not find the "other" man, they just happened to be in the right situation at the right time, and the "other" man caught their attention. The difference is that H has a sad ending, but OTWTTA has a happy ending, though not seen, just implied. And another thing, H is kinda steamy, but OTWTTA is more conservative, I don't know how they did it, but it came out nicely and sweet. H is also sweet and nice, but more sexy in my opinion.

Two people are just drawn to each other despite social norms dictating that they should not be together.
