3 couples from one bar.
1. A newcomer wants to accepts a player offer to try sex (which wasn't directed to him). Nonetheless, the two goes to a motel and have sex. Banri wants to meet Masaomi again, but Masaomi informs him that it was a one time thing because he is engaged. The two is separated by Banri cannot forget Masaomi and realized he was a rich family's son. One of the regulars at the bar works at the company and asks Banri why he was chasing after Masaomi. Long story short, Banri reaches out to Masaomi as friends because a relationship wasn't going to work anyway. But the two falls deeper into each other and Banri cannot let Masaomi marry. He whisks Masaomi from the engagement dinner.
2. The regular who helps Banri and Masaomi is in a predicament as his strict and hard to read secretary is actually gay. Not only that, he steals away his type. Turns out, it was the secretary's way of getting his attention and just after letting the president watch him have sex with someone... He goes on to the president and tells him all about the trap he just set up.
3. A train station worker saves an ill man at the station and lends him money to get home. He was warned that it might have been a scam. Nonetheless, he wants to meet him again. When they did, turns out that it was mutual.
(absolutely no closure for what happened with Masaomi's engagement. The secretary basically had sex with other people just to get the president's attention and where the hell did the boy he had sex with suddenly go? The train story happened so fast, there's no chemistry)
