The idea was great ! The plot and cast were all so amazing.
the one thing that made me give 10 to casting was Mob's facial expression. He made the whole series 10 x funnier and really liked how he would predict the scenarios.
It was too little to no intimate scenes in this series, but believe me, YOU WON'T REGRET WATCHING IT, specially if you've watched a handful amount of BL series.

despite being a 4-episode series, I felt it's longer. I really like how japanese series can develop the story and characters in such a short amount of time.
overall, make sure to watch it.
I liked it so much
