Tsurezure Children, Nande Koko ni Sensei ga!? Recommendations
Short duration anime, has an element of comedy, also featuring several characters in establishing love relationships them
Series of relationships, include episodes for specific characters, short episodes, and has comedy in both animes
but "Nande Koko ni Sensei ga!" has multiple ecchi scenes which can be considered as borderline hentai
It's similar in episode Duration. But aside from that. It has a different plot where the funny and romantic relation between a teacher and student. Also the plot is very funny (If you don't mind the Ecchi-ness).
Hence I recommend this one.
