I Wanna Think He's Just My Roommate

My roommate is a real angel. Makoto works hard at her job, but home she is lazy. At least until Makoto's younger childhood friend, Wataru, unexpectedly moves into her house. Wataru cooks and cleans and takes care of everything...... The only problem is that it's all too good to be true, and if it keeps going, Makoto won't be able to imagine life without Wataru! A naturally angelic boy descends in a pampering comedy with 120% healing! (Source: Comic Polaris, translated)
