considering this movie came out in 2015, if you're watching it now, it might feel kinda weird but honestly, it's funny. being friends and growing up together, it's understandable they feel safe and comfortable with each other. but yeah, Rita started all this because he felt sorry for Achida and didn't realize how much he actually cared for Hatori. but I'm glad Hatori and Hiromitsu Kosuke had their time together, doing fun stuff, and Hiromitsu Kosuke was brave enough to ask about Hatori's true feelings, showing how sincere he is. Hiromitsu really loves her, then Hatori and Rita are better together, while Hiromitsu Kosuke deserves someone better!
