Do You Really Know Yourself?

Mr. Senda asks Rumi to give a letter to someone he hated through his distant relative, Nogi Yuta. After he died, Rumi tries to find the person, Hanafusa Chiyo, herself. She can't find Nogi Yuta and finds out that Hanafusa Chiyo already died, three years ago. She then goes on to find Nogi Yuta in order to give him the letter. Shunya confesses to Rumi, but agrees to be friends for now. Chinatsu tells Rumi not to worry about her in order not to feel conflicted about Shunya. Meanwhile, Hatano realizes that her resentment toward Saeki is due to her own behaviour of forcing herself to work harder.
