It's been a while since I've read BL manga with a coherent story and with an original setting like this one. I really liked that it's nothing overdramatic, but you still really sympathize with the characters. Also, everyone said and I concur -- this manga is super cute and touching as hell (⌒▽⌒) It's also somewhat inspirational, esp for those super shy introverts like me.
Despite that I started to read it bc of the yaoi tag in the first place, I think that the sex scenes in the end were unnecessary.
Who would think that this story will end like this... OwO I'm not sure I liked the way the story was finished. As someone already pointed out, both Shou and "Prince" hated each other and I don't see how it could've worked out. I actually laughed out loud when I saw how Sensei "solved it". Maybe it's because the manga is too short and there was no room for development. But it's called yaoi for a reason, I guess ╮( ̄▽ ̄)╭ I liked the characters and all the sex scenes were super hot except the last one, so I think it's worth checking out, as long as you're okay with blackmail/rape.
