Hanamaru Youchien, Mitsudomoe Recommendations
they are both about kids and their teacher..Hanamaru is light-hearted and cute while Mitsudomoe has scary(in a funny way) and older characters and consists of mostly sex-jokes...if you watch Hanamaru and want a cute show then I don't recommend it...
Kids are really weird, and try to get the teacher to fall in love (Ayu with herself, the triplets with the nurse) in extremely weird ways. Mitsudomoe is very perverted, and Hanamaru is very innocent.
both about new teacher and kids [=
but in Mitsudomoe it's school kids and in Hanamaru Youchien it's Kindergarten kids .
both revolve around 3 girls and their teacher and both have dirty jokes, basicaly the same just with an age difference.
