Kokoro Curtain

Synopsis

Do you know what is love like? Kagami is finally able to confess to the one she has a crush on for a long time, Shuuhei-senpai, but it turns out bad when Shuuhei-senpai dumps her and says that it was not love that Kagami has for him. While Kagami keeps thinking about what love is, Kagami meets Toochi Eda, another carefree senpai.(Source: Shogakukan, translated)
