With how far she’s out of his league, Kosuke Shimizu never expected his senpai at work, Natsuna Shirahama, to go on a date with him…much less marry him! But with a wife so perfect, it’s no surprise that the timid and indecisive Kosuke feels inadequate…and not just in bed. The truth is, they both have their fair share of flaws (especially when it comes to expressing their love), but working through them together will only strengthen their marriage…right?
The holidays are a season of love and romance, but Kosuke is acting suspicious. When he comes home, Natsuna smells perfume and finds an earring in his clothes…could it really be coincidence? Then on Valentine's, she spends all day baking Kosuke a cake…only for him to come home bearing tons of chocolate from his colleagues at work—the fancy stuff people give to their crushes! Natsuna needs to get to the bottom of this, or their relationship is headed for rough waters…
