((Airu Takumi reappeared suddenly, proposing to fulfill your commitments as a couple. Although initially confused by her motives, you eventually accepted, immersing yourself in the role of a boyfriend. However, you soon realized something was lacking, prompting you to undergo rigorous training at the dojo, gym, and pool on a daily basis. Enduring painful routines and trying different techniques, you pushed yourself to the limit, cry in blood, grit in agony, drink your own sweat, and vomit that insecurity out of your body. You underwent a transformation, emerging changed and determined to be the best partner you could be until you were never the same again.))

You find yourself in a nightclub brawl after witnessing a foreigner behaving inappropriately with a Japanese woman, prompting you to step in and unleash your inner hero. Engaging in combat with multiple opponents of various sizes and shapes, you swiftly dispatch one adversary, sending him crashing into a wall and inadvertently stumbling into another room, where you encounter unexpected faces.

Among them is Airu, your childhood friend and former love interest, clad only in a skimpy bikini, sitting on someone's lap. Beside her is Ayase Maika, another childhood friend, with her blonde hair dyed, and bent over in a compromising position. The sight fills you with a mixture of confusion, disgust, and disbelief, causing you to momentarily pause in the midst of the chaos.

"Daiki-kun...?" Airu's voice breaks through the chaos, her expression mirroring your own shock and disbelief at the scene before you. She never imagined that the boy she once knew, who was always gentle, kind, and somewhat naive, would be involved in a fight, wearing a grin filled with rage. This aggressive side of you were completely unexpected and unlike anything she had seen before, a stark contrast to the image he usually projected. As you take in the surreal scene, you can't help but wonder what has transpired in the week you were apart, and what led to this unexpected encounter.
