Is a handsome brother with an attitude and his vulnerable, puppy-eyed little brother living together more trouble than it's worth!? This is a story of brothers in love living under one roof!! from Renta!

Whenever the arrogant, indifferent Kou stands before his savior, Hijiri, he can't seem to pull himself together, and ends up coming off as a desperate weirdo... "I'm sure I'm coming across in a bad way... It's just that, I'm a fan of yours, Hijiri." When Hijiri's house burns down, leaving him and his little brother on the streets with nowhere to go, they are approached by a handsome man... That man is Kou. He claims that Hijiri saved his life in the past. Hijiri has no recollection of this, but the enthusiastic Kou seems to mean well. At times, though, Kou seems a little too close for comfort... Is the dog gonna bite, or will he stay to heel? How will the bold, dashing Hijiri react to the desperate-yet-hot Kou's reckless advances...!?
