Rockabye Dear

"I want to give you everything you want.''

Yahiro is the second son of a wealthy family running a large hospital and spends his days with reckless abandon. The only thing that matters to him is his childhood friend Rui. Although Rui feels inferior due to being adopted, Yahiro has taught him that it is okay to rely on him. The two of them spend their childhood together and eventually began to become physically intimate with each other. Their relationship was maintained in an ambiguous balance all this time, but when Rui’s adoptive mother announces that she is pregnant, he suddenly says to Yahiro that they're done!?
