When reading drama, I like it when characters experience intense emotions, love, friendship, heartbreak, jealousy, anxiety, anger, and so on. Whatever happens, I win
(plus the girls are drawn beautifuly, and honestly, that's what I look forward to the most)
The annoying drama that frustrates me happens, when characters act stupid and out of character, here we have a classic childhood (highschool) friend, who probably fell in love with MC who has another girl on his mind, normaly we see this trope played annoyingly, but we just went through tons of setup for it, so it makes perfect sense why is everyone acting the way they act. (also, funnily enough, the reason she is atracted to him is partly because he didn't felt romanticaly atracted to her, since she had so many bad experiences with other boys who did)
I undestand the displeasement of most, but I feel like the plot made a good job at setting our expectations a certain way, I suppose that too many anime plots with simmilar events made it a bad asociation that makes people mad no matter what. I think Ayaka testing MC is pretty sexy and spicy development, Im honestly happy where the story is going, I hope MC and Kohai marry at the end too.
