I am Yusuke, and due to the nature of my job, I often visit my partner's company. I was attracted by the beauty of the receptionist here. I approached her to get acquainted and invited her to dinner and to watch a movie; she agreed, and soon after we officially started dating. Now we are preparing to get married, with the wedding set for mid-June. I am very happy and proud, as everyone has to envy me for marrying such a beautiful wife. But that happiness was quickly replaced by embarrassment, awkwardness, and humiliation. Nomoto is a long-time acquaintance and partner of mine. He is 5 years older than me, works in sales for a lingerie manufacturing company, is eloquent, and is a true playboy. He is very close to Aki, and the two of them always laugh and joke with each other even when I am there. But I thought it was just Nomoto's cheerful personality, and there was nothing more to it. But I was wrong! At the end of May, the golf date with the partner was canceled, so I bought cake to Aki's apartment and wanted to surprise Aki, but I accidentally witnessed a scene that I couldn't believe!!! She and Nomoto were happily doing that together!!! I tried to hold back because the wedding was about to happen, but everything was going beyond my limits! Forcing me to make her choose: Me or him!!!
