Someone mentioned in the comments that it doesn't really become a BL until around 209, but prior chapters are character and relationship building.

Dream Away
I really enjoyed this series. Lighthearted where it counts, and the pains I felt were good pain. I wish we could see more of the second couple but I think this series was simple enough that ending things where they did worked just fine; a very cute series overall. Official on Lezhin, officials are here, but lots of the chapters are cut up weird and/or missing panels, read on Bato. It's shounen ai but the author posted an extra, on Bato people posted it on chapter 37 Series info: https://www.mangaupdates.com/series/v8sp9q7/dream-away Bato: https://xbato.com/title/84991-dream-away 5/7/25
