and say "Taekyung, I want to make you suffer" because that's the only way his current actions would make sense 🤨

who will always retaliate by doing the same thing: sex.
And while S1 Heeseo's goal was clear (staying together with Taekyung and earning his acceptance) and his actions were usually aligned with that, I feel like S2 Heeseo should just stop pretending to care +

He'd use his own trauma against Taekyung and wield Taekyung’s own weaknesses against him. Teen Heeseo was more susceptible to emotional damage (Taekyung’s strong suit) but he was also more chaotic and way more entertaining to read.
Adult Heeseo is just an emotionless bully +

Tbh I can't even imagine Taekyung jerking off to Heeseo specially after his reiterative refusal to engage in sex with him but I agree with you, he might be asexual... And I'm curious about where this thing with the stepbrother is going

Ik but it'd make an awesome plot twist

As far as I've seen, Taekyung only ever initiates something when he's coaxed/challenged or when he feels like he's in *control* (ie when Heeseo behaves more like an obedient child) but he doesn't seem really interested in sex in general. Also, Heeseo has this idea "sex = love" 🫠
