I can't say this title is exactly the same subject of jdrama but it has vibes of age gaping subject and affair of younger boy and older women. And a little bit cheating ?

Older lady and Younger boy relationship that will end up to happy ending and being with together for like forever. And even wedding and marriage.

Both are set in an alternate historical world in which there is a magical race of people with unique powers. The leads are a star-crossed romance between one of the race and a human.

Simply because it has the same ML and I am in love with him. But seriously if you like him in this drama I recommend you watch Sweet Teeth he becomes interested in the FL really fast, and there are just the right amount of jealousy scenes.

A kind but strong FL falls into the clutches of a rough and tough ML. Kidnapping, escapes, and a crazy sister. It's a wild ride, with great chemistry between the leads.

In both series Male lead cant recognize the people face
In both drama Female lead role as assistant and further they become lover
In both drama female lead help male lead and support him in all way

both have badass female leads with an ulterior motives and a backstory behind their doings. jiwoo was revenge driven in my name who wanted to avenge her fathers death. after a series of events she gets to know that the person she joined hands with is the real killer and that aggravates her thirst of killing. i feel like the protagonist of this drama also has a similar story.

Similarities:

- Secret crushes
- Both school-related plots
- The "nerd" ML gets a makeover
- Each ML helps the other ML in some way (secretly)
• Tries to become their friend too
- The ML's friend helps the ML get their crush

Differences:

- FUTS ("Fish Upon the Sky") is university-based while MSP ("My School President") is high school-based
- MSP is more about music than school, while FUTS is more about dentistry and health sciences (medicine)

they both had girls who were sold off by their family to repay debt owed. Cubic the man was a mafia in hong kong.

In both, apart from depicting gay puppy love, one of the male leads is the singer of a high school band and, therefore, music -and their countless OSTs- is a key point element through the whole story.

Both have firefighters and leads who work in life-saving professions. Both are slow burn romances in which the FL falls first.

Both have one or both of the leads in life-saving professions. Both FLs admire/crush on the MLs at the beginning when they save her, and both MLs are established in their careers whereas the FLs are still in school/starting their careers.

Both have a main character who goes into an alternate universe where they are married and have children.
Welcome to life is about law while switch is about actors.

I found both stories pretty similar so if you liked one of them then you will surely like the other.
Differences:
Body/World swapped
Switch male lead is actor
Wonderful nightmare attorney

watch this if you really like the small-town/country vibes of this drama. I
It's very chill and relaxing and it does have some other subplots, but it is very slice-of-life focused.
(subplots include some romance and a mystery)
