Am I the only one who found Saikawa's (seme) feelings weird? Like, I'm not saying that in a bad way, but the story doesn't really tell you why Saikawa liked Sayama(uke) in the first place. Like Sayama had a full chapter (or something) trying to discern his feelings for Saikawa, and then Saikawa just barges in like "I think I'm in love with you."
Or was it because Saikawa is secretly a sadist and likes to tease Sayama, then accidentally fell for Sayama's cuteness uwu (づ ̄ ³ ̄)づ
Maybe that's because I missed some parts of the manga lol. Anyways this is really cute kjsdhfjkfhja ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
Sayama is that boy who always wear a mask and never interacted with anyone and Saikawa is the opposite, always friendly and polite with everyone out of formality/habit. When Saikawa coincidentally interact with Sayama, he was surprised that Sayama is actually a foul mouthed loud person. Saikawa found that it was interesting and started to tease Sayama to get some reaction. After a long interaction, involving his tutoring and the past with Kobayashi, Sayama started to open up and Saikawa started to become greedy...
I love how this manga seems to be just smut but has actual story and an equal amount of drama ლ(´ڡ`ლ)
