The first chapter is not very riveting, weird even. But from the second one onwards it is interesting. It's a combination of humor between a scary servant and a cute young lady who is not affected by his strange presence.
I felt like there was an ulterior motive behind his behavior, but his unique oddity to attract the hearts of others in the context of brainwashing worked well: how their small battles took place to influence and not be swayed by each other. And compared to Sakamoto, who is more perfect, Kuki (the servant's name here) emphasizes more brash, indifferent, and eager to interfere in other people's problems.
It’s interesting for me, with this typical sol shounen. I simply enjoy it and hope you too!
