Prolly one of the best yaoi out there (imo).
You can really see how the author actually worked a lot on the plot, dispite it not being the most original I've ever read, it's well built, the characters are all quite pleasant, even if they don't match your personal taste.
No rape or any kind of abuse are represented, the relationship is clear and healthy.
Nothing more to say, if you're willing to try reading this, it's highly recommend.
That sunbae is gonna get punished, we all know.
