What yaoi is this?

I think it's incomplete but i just loved the art I think it was about a senpai (seme) who needs his kohai (uke) to teach him simple math because hes failing really hard and the uke would think of him as a dog (if i remeber correctly he would give chocolates to him if he well? idr) anyway the seme could cook really well and feed the uke i remember a scene of them kissing and the uke said "kissing felt so good" and that made the seme blush I hope this helps its been bothering me since its been years since i last read it so I can only give some vague details If anyone knows plz tell me ^^ THANK YOU!
