Recommendations Age Gap Relationship

Good day everyone
I'm looking for some manga where the Mc and Main love interest has a age difference between the two of them
Like teacher-student relationship or something along those lines
Well my main reason for looking for something like that was because of this manga:
Senpai ga Urusai Kouhai no Hanashi

Hope you guys could recommend me something good, thanks

Edit: Anime's are fine too
Edit 2: Minimum age should be around Teens/High School age and the Oldest age around middle age/look

 

I don't have a recommendation, but I came here to warn others: Don't recommend Usagi Drop. I am going to find you, and I going to kill you.

 

We have a Mango Drop dropping by

 

Drat

 

Killer nights, but be careful it's not for the faint of heart

 

Are we talking smaller differences or differences large enough to be generation gaps ?
And how much is appearance age and how much is actual age going to change things?

 

I edited my OP, and I'm just hoping that I could find something like the manga I posted earlier

 

I recommend Usagi Drop

Immortal rain- the gap is a few hundert years but the ML still looks like a young guy in his twenties- it is fantasy but GREAT (i swear) and completed

There's a new anime this season "after rain" i think is the title. About a highschool girl and a middle aged cafe owner where she works at. She has a crush on him but hes oblivious (not the beta make idiot kind of oblivious)

 

There is Gal Gohan. It's about a young High School teacher that does home ec and I think a 2 year high school girl.

She is actually kinda dumb but, that's just when it comes to academics and she is actually a pretty sweet gal.

Sadly, it's kind of a pseudo-harem. Meaning there are few girls that like him but, he doesn't actually like them that way at all. He is a little dense but it's just cuz he's a teacher and doesn't have those (atm) kind of thoughts.

 

Sensei lock on is good n funny

What about a classic like Legend of the Condor Heroes
