Kanojo Okarishimasu 27 Summary and Translation by BakaData.com
The idea Kazuya came up with is to tell everything to Kuri. Kazuya tries to escape from the window to go to Kuri’s house. Mizuhara asks him if he’s really certain that it’s the right decision. Kazuya explains that it’s not fair that he knows Kuri’s secrete but Kuri doesn’t know his secret. Kazuya is excited that the two will be able to drink together and have a discussion about rental girlfriends.
As Kazuya goes out of the window, Ruka comes in the room, causing Kazuya to fall of the tree. Ruka is shocked that he tried to run away. Mizuhara is critical about Ruka’s actions. But she argues back that Mizuhara doesn’t understand how much she has been looking for someone like Kazuya.
Kazuya knees on the ground and begs Ruka to forgive him and stop it. He apologizes if he made her misunderstand and she’s free to punch or kick him. He explains that even if her feelings are true; he cannot allow this to happen when he considers Kuri’s feelings. But then Ruka starts to cry.
She says that she knows that her actions will make him hate her, but she couldn’t do otherwise after finding out Kazuya and Mizuhara live so close to each other. She then says that it’s okay if he doesn’t like her right away but she would be content with a “trial period”. Mizuhara looks like she has given up and tells Kazuya to date her. She explains that Ruka won’t go home and she also knows where his university is, so letting her roam free is too dangerous.
Mizuhara: “She says it’s a trial period anyway…Okay?”
Kazuya: "2017…October….31st…at 17:17…And this is how I got a (trial) Girlfriend."
