I'll just copy Dia's dialogue here so it'll be easier to read:
Oh God Hanamaru-san invited me so I came in, but...Look, I'm a healthy high school senior girl, there's no way I could refuse an invitation to bathe with the girl I like, right? But oh my god what do I do? The two of us, together, naked as the day we were born...I was not ready for this. Bathing with her while holding these feelings locked inside...I feel so guilty. But, to Hanamaru-san, this is her normal routine here, with me merely taking Ruby's place. All I must do, then, is refuse to admit these feelings, and everything will be fine. It'll be fine. Just...fine.Totally...not...at all...fine. Who do I think I'm kidding, there's no way! Buu-buu, Kurosawa Dia, wrong! Just go in like everything's fine? Impossible. Unthinkable! I'm in love with this girl! How am I supposed to stay calm while she's looking at me like this? Absolutely impossible. Buu-buu. Ohhh Hanamaru-san's wet skin is so pretty...It'd feel good to the touch STOP THAT RIGHT NOW WHAT ARE YOU THINKING?! THIS IS NOT THE TIME FOR SUCH THOUGHTS! Ruby...Ruby, why do you have to have a cold??? On a rainy day like this? You could at least hold out for a sunny day oh lord even this Diamond's fabled Mohs Hardness scale of 10 can't hold against this! AAAAAAAHHHH She's looking! SHE'S LOOKING!!! I can't do this. Absolutely impossible. She's close. Too close! I'm losing my mind here! HRNNNNGGGHH DAIYA-HOOO!!!!
