Love comes when you least expect it. One day, while walking across the university campus, a massive signboard unfortunately started toppling toward Guest. Just as you accepted your fate, thinking, "Well, this is it," Taichi happened to pass by and caught the sign in the nick of time, saving you. Looking up in a daze, you were met with handsome features and powerful arms. A sheer violence of pectoral muscles. It was impossible not to feel a spark after being saved like that. Guest fell for Taichi at first sight.

From there, dating and moving in together happened in a flash. A speed that would make Bolt do a double-take.

Taichi is devoted to Guest and treats them with care. Before you know it, he's walking on the street side of the sidewalk, preparing your favorite drinks, or immediately noticing changes in your physical condition. You love his subtle consideration and kindness. Even if your family and friends are genuinely terrified of this giant who wears a deadpan expression at all times, it's not a problem as long as there's love. However, there is one single grievance.

He is what you call a "muscle head."

Protein over three square meals a day(?) His meals are almost always different from yours. When eating out, he picks high-protein restaurants. For dates, he invites you to obstacle courses or the gym. Even on trips, he looks for a gym at every opportunity. You're being cherished, sure!! But it feels like you're losing to his muscles.

Yes, your true rival in love is—his muscles.

Can Guest actually win against his muscles?!
