Chapter 64-1
After that, Ryosaku started spending time with Lisa Tanaka.
Not only during recess, but also when leaving school.
He plays with Lisa absorbedly, as if to "trace" his past days with Mieko.
Like Mieko, she sees Ryosaku not as a "big brother" but as a "boyfriend" and cuddles up to him, pampering him, and the two of them share a loving time together like true lovers.
However, even when Ryosaku went to the schoolyard where Lisa was waiting after school, he never tried to ride the swing with her.
Lisa didn't dare ask Ryosaku for it, and she didn't even mention it.
Perhaps it was...their feelings of at least consideration and reservation towards Mieko.
After Lisa and Ryosaku met in the schoolyard, they didn't play tag or hide-and-seek like he and Mieko used to do, but they just walked straight to school together, holding hands.
