Chapter 62-1
After receiving a message of encouragement and the most loving message from Yoshiko's teacher's mother, Ryosaku vows his unwavering love for Mieko, bids farewell to his mother, and heads out the door.
Waiting there was Mieko's old best friend Lisa Tanaka.
Instead of returning to the bus with everyone else, she waited alone for Ryosaku to come out of the house.
"...Lisa-chan. What happened...? What about everyone else?"
"They've already gone to the bus and are waiting for us. Ryo-chan, come back to the bus with me."
Lisa said, holding out her left hand to Ryosaku.
Before he knew it, Ryosaku's nickname had changed from "Ryosaku-san'' to "Ryo-chan."
