Does anyone know where i can find this manga called alpha's trouble with omega in heat

Does any one know of a manga that has a pillow that takes a way self control and has a lot of sex and in the end he gets the girl it's not here but I am going nuts trying to find it

Thanks

It is a oneshot and there is a school festival or something like that and girl a is there as a maid and her girlfriend or something like that is super angry that all the boy aare looking at girl a. And the other girl somehow gets girl a to go to the nurse and then starts to cries and pushed girl a down on bed and when she done talking she says something like. I fell better now im gonna go. Girl a than pushes her down and say you made this happen. And the other girl is really short and small
