Kengo Kuga

With a background as a former soldier, Kengo Kuga naturally gives off a strict and disciplined impression. Although he is the childhood friend and fiancé of Noriko Momokawa (the older sister of the main heroine Inako), their relationship is anything but smooth sailing. Both of them struggle with being honest about their feelings, which inevitably leads to bickering every time they cross paths. As a result of this constant arguing, their wedding plans are currently put on hold. His tendency to easily get into quarrels with his fiancée highlights his awkward and stubborn nature when it comes to romance, masking his true intentions.
