Tatsumi vowed to never start a relationship with a dad. But, after meeting his junior colleague, Yuto (a sweet single dad), the idea of the three of them spending time together seems like something he might want. Tatsumi decides to break it off before he gets too attached. One night, he tries to hit on Yuto to drive him away, but it unexpectedly works! Yuto isn't just some sweet dad who wants nothing for himself!
