This volume opens up with Mayuka and Ren talking on the phone. We find out he is quitting the café to get a job closer to her, so they can see each other more. We also see Ren trying to distance himself from Ninako again, probably thanks to Manabu confronting him about his feelings in the last volume.
Ando and Nikami go shopping together for the Christmas party and stop to eat. Ando’s ex-girlfriend shows up, and he reacts pretty emotionally. He’s so distraught, he decides to skip out on the Christmas party. Later on, Nikami sees Ren working at a gas station, and she wonders why he’s not with Mayuka on Christmas, but he’s all alone. She experiences inner turmoil over her feeling for him and wonders if she’d be using Ando if she went out with him to make the pain stop.
After Mayuka and Daiki meet with their dad before he moves, she calls Ren late to meet her outside her house. He reassures her he will be there for her during this difficult time, but when she does back in the house, she tells Daiki she wasn’t so shocked over her dad remarrying, but shocked that she wasn’t that upset.
Ando shares more of his story about his ex with Ninako. We find out she just used him to get to his friend, she didn’t actually care about him. And then one day his girlfriend tried to kiss his friend, and for some reason he still got mad at said friend. He explains he lost both of them, and it was his own fault. He also says they aren’t enemies or anything, but they can ever be as close as they were before. Of course, Ninako erupts in tears over this sad story. He tells her she’s dumb for crying about someone else’s problems, but then wraps her in his arms and says it’s also what he loves about her. At that exact moment, Ren comes in.
Ando propositions Nikami again, he tells her the next person she falls in love with will be him, but Nikami isn’t so sure. Later for some reason Ando tells Ren, and asks him if he will fight hi m for her. Ren says he will crush his feelings for her.
This volume ends with a bit of a shocker, Mayuka breaks up with Ren! She realizes she isn’t being fair to him and that she can tell he has feelings for someone else, but he is too noble to give into those feelings. So she lets him go.
The bonus chapter goes more into Ando and Ren’s backstory, and we discover, he was the friend his ex used him to get close to. We also see this is what led him to his playboy ways.
