Looking for a Shounen-ai

It's about two actual brothers with an 8 year age gap. The eldest that is 24 went to study in a city since he turned 16 and left his 8 years old brother in the village. They meet again when the eldest is 24come home to visit the younger 16 and start to develop feelings for each other but both stop because they know it's not right. They kiss when one of them is sick because the other's trying to feed medicine to the other then the older leaves the house I think. In the end I think we see them living in the same house. Please help me find it!! It was the sweetest incest story I read. Also it has a small number of chapters and has something like oni-san in the title
