I Have a Crush at Work

Tateishi, a man in his 30s working in the accounting department at a confectionery manufacturer, and Mitsuya, a man in the planning department, start dating in secret from their workplace. The two start a new life at the office, but Mitsuya is worried about what his colleagues think and becomes stubborn towards Tateishi. Meanwhile, while on a date, the two accidentally meet Suzuki, a lecturer at their new employee training and Mitsuya's senior from university, and the three of them go out to eat... As they face the difficulties of maintaining a secret romance, what will become of their love?

Invited by Hayakawa, Tateishi and Morizono go out for drinks after work. Meanwhile, Mitsuya is also attending a launch party for a new product competition, and they happen to run into each other at the same izakaya. It turns into a joint departmental drinking party, and although Tateishi and Mitsuya are anxious, they decide to get away with it. However, Mitsuya cannot bear the awkward distance between them, and ends up drinking too much and passing out. Tateishi tries to look after Mitsuya out of sight of others, but...

When Tateishi visits Mitsuya's house, he is excited to see her room filled with her favorite things and an unexpected side to her that he doesn't see at work. The more they get to know each other, the more they are drawn to each other, and their relationship deepens. One day, Tateishi visits the warehouse in search of documents and happens upon Mitsuya, who is organizing the warehouse by himself. Mitsuya slips off the stepladder, and the two end up in a position that looks like they are embracing each other, gazing at each other.

Mitsuya is disappointed by the low sales of a product she planned. She tries to compensate with an ad plan, but her boss gives her extra tasks, which mess up her schedule. Meanwhile, rumors spread that Tateishi is popular among the female employees, which makes Mitsuya feel insecure. Later, at home, Mitsuya tries to seduce Tateishi, but he flatly rejects her. She pushes further.

Tateishi and Mitsuya get into an argument over where to go on their first trip. Tateishi is in favor of Hokkaido, while Mitsuya is in favor of Okinawa, and their preferences are polar opposites, so the argument goes nowhere. Despite some unsettling moments, they decide to go to Yamanashi, Tateishi's hometown. However, trouble occurs the night before departure! A delivery error is discovered in the planning department's new product, and Mitsuya is suddenly forced to work overtime... Will the two be able to depart on their trip safely?!

Mitsuya submits a proposal for a new product competition to his superiors, and although he is told there are areas for improvement, he steadily moves forward with the plan, step by step. One day, he attends a meeting with Kiribayashi, the head of the new business division, who is rumored to be an extremely talented person within the company. Kiribayashi has a high opinion of a product that Mitsuya had previously planned, and invites him to join the new business division. Mitsuya is confused by Kiribayashi's unexpected proposal. Mitsuya is torn between staying in the planning division or transferring to a new department.

Tateishi and Mitsuya have been dating for six months. As their anniversary approaches, Tateishi begins planning a surprise for Mitsuya. He chooses a present at a department store and secretly makes preparations while checking his smartphone every night. However, Mitsuya is growing increasingly worried as Tateishi seems different from usual... Will Tateishi's surprise plan be a success?

One morning, Hayakawa from the accounting department and Somei from the planning department were having breakfast at their usual cafe, excitedly talking about their favorite bands. Hayakawa was gradually looking forward to spending time with Somei, but it seems he has some trauma from a past relationship... Not wanting his feelings to grow any more, Hayakawa decided not to go to the cafe. Somei noticed Hayakawa's behavior and...!
