It's been almost a month since our heroine and Sakaki began dating. On their lunch break at the cafe, someone arrives who seems to be a little too familiar with her. It was her ex-boyfriend from university, the root of why she hadn't been in a relationship for so long. As if being stylish, handsome, and great at his job wasn't enough, it seems as though he's been invited to our heroine's company to discuss working on a collaboration with his brand. When Sakaki asks about their relationship and learns he was her ex-boyfriend, he pulls her into an empty storeroom, grabs her arms, and starts to kiss her forcefully... "Did you do this kind of thing with him too?" While she is at Sakaki's mercy, her ex-boyfriend's voice calls out from behind the door... Angry that Sakaki would do something like this while they are at work, our heroine puts a little distance between them. But when she sees how unhappy Sakaki is... "I didn't express my feelings for him clearly enough... so he must be feeling insecure, right?" She thus decides to tell Sakaki how she feels, and sends him a message to meet up and have a talk, but... with no response from Sakaki, times simply passes by. Is she perhaps too late...?
