From Starry Sky Scans:

“Your opponent: a BABY + Current state: a lot of PANIC = Result: a JOYOUOS occasion!”
Konno Wataru, a rich son who is studious and quite prideful, has a “butler”. In charge of him is the domineering sadist Azuma ヽ(#`Д´)ﾉ, holding an official caretaker license and to top it all off, he’s perverted (?!) Amidst their instinct of a cat-dog relationship, things get a bit risqué ❤
—During which, Wataru’s older sister’s baby, Momoka, suddenly appears! With a MIA father, Momoka’s care is left in their hands!
In between the teasing, puzzled Wataru unexpectedly witnesses Azuma’s sincerity ❤ …however…?!
