I feel the same! There's something off about him. I don't get how but there just... is.(?!)
(Sorry, I accidentally clicked annoying instead of reply the first time.)
That look in his eyes here. http://www.mangago.me/read-manga/crackster/mf/c001/25/
It's that kind of look like he's getting exactly what he wants. I don't think he's innocent or like the "idiot" he appears to be. He kind of came off to me like a cunning guy. Then again... I could be looking too much into things here. There's the title of this story that's throwing me off too. What exactly does Crackster even mean.
(I'm probably just hoping for things to get dark but I doubt this mangaka would take things that route, haha.)
I totally see where you're coming from, like love manipulation, but not malicious--probably with some "I will get my man by whatever means bc I love him but he's straight" sort of cunning nature. And actually I can get on board like that, because it's a refreshing take on the seme/uke where the uke is in control more than you think! (๑•ㅂ•)و✧
For the first chapter, that was actually pretty good. I got hooked right away and this definitely looks promising. Although I got this strange vibe coming from Mio. Like he's not only hiding his sexuality or obvious crush/love for Shino... but like there's something else there. Anyone else get that kind of vibe from Mio?
Anyway, I look forward to future chapters.
