Mamiya was harshly dumped by her boyfriend for "incompatible bedroom chemistry," so she downloads a dating app to lift her spirits and search for a man who suits her. To her surprise, the first match is her coworker Sakuma. Though they part ways after an honest conversation, Sakuma remembers Mamiya mentioning she's interested in another coworker, Iwamoto, and soon invites her for a three-way drinking night at his place. Caught off guard, Mamiya hesitates but begins to sense the start of a new relationship dynamic.
