The brown haired guy is a pushover and the actor is very unlikable (for the 3 chapters I've read) even outside of the blackmail so yeah it's a no for me I can't even finish it.
(I'm sorry but brown haired being like "omg he is so caring of others and diligent in his work kyaaa" just bcz sora is learning his script which is his job, while kakeru had to stand in an 1 hour long waiting line just to get him his favourite dish + take his class notes for him is fucking ridiculous , that boy is a victim for real he suffers cognitive dissonance)
