This relationship feels complicated. Judging from the images and some dialogue it is clear Tae loved Heeseo even back when he was still 19 as he admitted to masturbating to him and regrets choices with Heeseo. (Clearly wanting the best for Heeseo). When Tae got kidnapped and graped, he did see it as disgusting and said he won’t forgive for it but it seems Tae can’t hate him because he feels partially responsible for how Heeseo turned out from how he treated him in season 1 with the lying and neglect. Heeseo on the other hand from the balcony scene always liked Tae and just wanted Tae to notice him, to point of hating him if it means Tae will notice and take his interest in him seriously. But when the balcony scene came the whole lie was over and Tae finally understood why Heeseo did all of that and hugged him and realized he does love Heeseo. I think it’s from that Tae started to reciprocate more? I don’t think the bj in the car was meant to be reciprocal bc they initially planned to go to the restaurant and Tae just didn’t want to get caught having car sex.
