help :)

Hey! I'm looking for a manga that i've read a long time ago but i couldn't remember the name of it. It was incest about two brothers , bigger brother left the city and when little brother starting to highschool or college their parents asked for him to come home so little brother wouldn't be alone. When they're little , little brother saw his brother kissing with some girl and got jeaolus and ran away. then he kissed his big brother too. I hope someone can remember it :)
