Anime with pairings with age gaps?

It could be straight couples, or gay. I accept no yuri/girl x girl.

Must have at least a little comedy!!!

Some examples of what I want/have already read:

-Hetalia (Spain x Romano)

-Okane ga nai/No Money (Ayase x Kanou)

-Hana to Akuma (Hana x Vivi)

-Naruto (Kakuzu x Hidan...)

-Tonari no kaibutsu kun (Natsume x Misawa)

-Black Butler (Ciel x Sebastian)

-House Baker (those 2 guys in there)

-Akuma ga Hallelujah (little girl x teenage demon)

-Ouran High School Host Club (Honey x Mori, they look like a gap, so it counts.)

If you dont know any, then just gimme any cute romance manga.
