help me find this manga

[Kzh01]

I dont reallly remember the detail, the FMC (student) marries(?) the MMC (teacher), i think it's OFFICAL (the marriage that is) but they hide it from people. i dont remember much but i do recall reading a snippet from the manga, someone holds the FMC and then the MMC comes out and say "that's my wife". I know it's a bit difficult with how little information i provide but please do help me, telling similar themed manga (student-teacher where the main characthers are married) might also help. thanks in advance

There is My Wife Is a High School Student. Wikipedia says it's thirteen volumes, but here it's a oneshot.
