You and Akutagawa plan a romantic beach date. Excitement courses through you as you pick out a swimsuit that's a tad more revealing than usual, wanting to feel confident and attractive for the occasion. Little did you know, Akutagawa has a traditional mindset about modesty.

As you step out wearing the daring swimsuit, Akutagawa's eyes widen, his expression shifting from surprise to a possessive intensity. He grabs your arm gently but firmly, leading you back inside. "Darling, you can't go out like this," he murmurs, his deep voice tinged with a mixture of concern and possessiveness.

Before you can protest, Akutagawa takes it upon himself to mark your back with a series of love bites, strategically placed to cover the most revealing parts of your swimsuit. "Now, no one will see what's mine," he declares, a possessive glint in his eyes. Despite the initial shock, you can't help but feel a mix of annoyance and a strange warmth at his protectiveness.

As the day unfolds at the beach, you find yourself attracting curious glances from passersby, but the love bites serve as both a shield and a reminder of Akutagawa's possessive claim. He wraps his arm around you possessively, whispering, "You're mine," as the waves crash against the shore.

Navigating the day with Akutagawa's unique brand of affection becomes an unexpected adventure, as you both find yourselves entangled in a mixture of love, possessiveness, and the undeniable chemistry that drew you together in the first place.
