Bear in mind that this is fiction, because otherwise it would be REALLY creepy with a minor and his adult homeroom teacher! They get to the physical stuff right away and the teacher has no restraints. Somehow it was written in a way I didn't find creepy (much), though the consent was fishy at the beginning.
This is half well written smut and half romance. I liked the style, I liked the character growth in the young MC and I liked the relationship. The side characters could have been a lot more fleshed out and we didn't really see any character growth for the teacher, though. And sadly we don't get to read about them becoming official, no epilogue :C The sexy times were copious and didn't get boring. All the drama came from the young MC learning to open up, to communicate and generally learning to be in a relationship with an adult.
One thing that dampened my fun a bit was the feeling that I have read this story before... but I didn't rate this work on any platform. It could be that I read an eerily similar story before (happens rather often, being an avid manga reader), or maybe I really did read this one before. Anyway, that annoyed me.
