Hi guys I need your help to remember the name of a manga; it's about this guy who has 2 kids, an older son and a younger daughter; he gets a housekeeper to take care of them called aki (I think) that is his kouhai from high school, he has long hair and looks like a girl and he doesn't get along with his family so he lives with them... One time he pretended to be the younger son's mother because they had a school activity that mothers were suppose to attend so he crossdressed... About the genre I'm not sure, maybe it's shoujo or josei. Thanks in advance for your help ^^

Boku Wa Ne, I think

Yeah that's the one!! Thank you very much ^^
