oh that's http://www.mangago.me/read-manga/passion_fruit_no_kaori_tsuki/#sthash.EL92CEkB.dpuf you can check my review for more details/which page the particular pairing is.
additional info maybe , the first time the seme and uke meet, the uke was mad at the seme because on the first scene, the father seme got separated by his kid, or the kid wa slost so the uke said somthing like he doesn't know how to take care of his child.
awwww that's it! Thank you <3
i'm pretty sure that's that. it's the third pairing with the curly hair sensei.
or if you want, you can check my BL with childcare list, i've specified the ones that has teacher and parent pairing http://www.mangago.me/home/mangalist/24154/
if I remember it right, the manga is composed of many stories which are interrelated. This is not the main story but I like it, the setting was a kindergarten or daycare (not sure) the uke is quite snobbish . The main uke and seme partners him with a father who brings his child in the daycare.. and the seme and uke didn't get along at first. I think the seme's son is quiet and antisocial? not sure.. please help huhuhu
anotehr story, not sure if it's the same manga or no, the seme puts a gun to the bag of his kid that goes to the daycare/kindergarten, the bag is a bunny design?
THANKSSS
