Jay is trying (in his own fucked up and non healthy/sane way) to heal Taemins "scars".
Taemin has been carrying his "guilt" as the sole reason for his existance. He transformed it into "revenge" after 5 years of self punishment and now focuses on doing anything necessary to achieve this "revenge", even putting his life in danger (he's suicidal, no doubt).
Jay after understanding Taemins intentions and determination, he has fallen for him and wants to "fix him", or at least "fix his focus to something else".
Jay understands that in order to genuinely help Taemin, he must "prove" to him his determination to "fix" Taemin... And considering how Taemin refuses to ask for help and risks his life for others, Jay is angry that his hard work is not helping him much, but rather pushing Taemin to further get into risky situations.
Jay is crazy lol he is def black flag but I love it, its so toxic and insane but damn, these characters and the story is all so good and well done ლ(´ڡ`ლ)
Taemin is a manly, strong and determined (suicidal) bottom, Jay is a stubborn, smart and impatient af top
Love their dynamic, can't believe it been less than 3 months in their time line and the manager and sweet guy STILL dont know Taemins bro and mom are dead... This is a slow burn but the delayed gratification is DELECTABLE AND SO WORTH THE WAIT (▰˘◡˘▰)
