meanwhile

chenle finally knew what miyeon wanted from him ; fame . he wouldn't say he was popular in school but that's exactly what the writer is saying .

jisung approached the lifeless boy and sat next to him on the bench . he handed him a book .

" you know yerin ? it's hers . pass it to her . "

jisung then left . chenle couldn't help but think whether she has written anything about him or not . he opened the book and began to read .

she did write about him . that's when he realised how long he's been ignoring her and how she's hurt by it .
