Sex is intimate, and for some, it takes everything to bare it all... so when Misuzu was told that sex with her was "boring," she gave it up all together... and dating, too. So when, years later, she's asked out by her colleague, Mikage-san, she screws up her courage and gives it a shot. But it turns out Misuzu isn't the only one with baggage around sex. Can the two of them work together to overcome their hurdles, and enjoy each other as the couple they wish to be...?

Misuzu and Mikage are two people who work together at the same office. They find themselves mutually attracted to one another and begin to date. They each have their own hang-ups when it comes to sex, but the two make a promise to each other that they're going to work hard to be able to have sex that is both mentally and physically gratifying. They decide to apply what they learned from having sex last time, when they stopped in a panic, and get it on. This time, they're deliberate, take their time, and teach each other about what feels good. During their tender time together, Misuzu starts to go through a change...? Two people who joined the company at the same time as Misuzu, Eiji and Anri, both don't appear to have ever had any concerns about sex, but it seems that they do...?

Following being told by her ex-boyfriend that sex with her was boring, Misuzu, age 29, became a coward when it came to relationships.

The truth is, Mikage has his own hang-up about sex. He can’t get hard when he’s nervous. Their bodies begin to entwine by taking things at their own pace and honestly telling one another what they want to do and have done to themselves. One night, amid a downpour just like the one the night they began to date, the two of them finally cross a threshold in a tender, sweet moment, and then—?!

Mikage had his own sexual issues to overcome, but as the two of them opened up to one another, they slowly became irreplaceable supports for each other who could talk honestly about all of their issues, inside and outside the bedroom. After attending an old coworker's wedding one day, Misuzu finds herself thinking about the next step in her relationship with Mikage, but does that mean...?
