This part of the review is spoilerfree. As the description says Cello Mellow is a collection of six oneshots. Each chapter follows a different pairing and story. Its not that long so you can finish the whole thing in one sitting easily. Overall it was a nice read. It wasnt bad. My favorite story was in chapters 5 and 6 the longest story of the group. Its honestly pretty surprising that Chapter 7 Cello Mellow is the main story of the collection rather than 5 and 6. Cello Mellow was my least favorite chapter which is why this is disappointing. There were definitely some sweet moments in there but there are a few really short chapters in here making those sweet moments very shortlived. Theres not much else I can say to keep this spoilerfree. The stories are short and good enough to where even if you didnt end up liking it you didnt waste that much time. A warning though: Chapter 7 does contain tiny snippets of scenes that may be considered more mature. TLDR If youre into very short oneshots this may be the manga for you. It was good but nothing that really stands out. Chapter Descriptions The chapter descriptions are just that: Descriptions. However I realize some people might not want ANY spoilers including descriptions so Ive marked them as a spoiler. Chapter Ratings Im not good with number ratings so Ill just write out what I thought about each chapter. This section contains actual spoilers to the manga so only read if youre okay with that.
