It's not you're run of the mill yaoi blackmail trope, it's much much better. The BUILDUP is CRAZYYY, these past ten days waiting for the next chapter on lezhin made me more bitter than these two ready-to-explode enemies going at it in the first chapters.... I wish I could throw all my coins at this author, it has all my favorite elements: slow burn buildup, the tiniest hints of sexual tension, double tsundere, dark tall and handsome seme (it's obvious), and personality beyond just being tsundere! Also, it's a really nice cherry on top to have DIVERSE characters.
