this is quite confusing... the smaller one is the bottom and the bigger one is the seme but the uke is a power bottom so he's beats up the seme but he still gets that dick and the uke likes seeing the seme in pain.
i hope its not that. and i dont think it is. but i DO think that blondie aka Lee knows buff boi aka Cha Jaehyun from earlier in their lives, like he's in some way alrdy familiar with Jaehyun but Jaehyun either never met Lee Sunjin before OR he did and forgot cause it wasnt a particularly memorable meeting for him. we'll see. maybe Lee just knows a good potential bottom bitch when he sees one. (i know i know he's not the Actual bottom but he is a sub so close enough~)
That's a very good theory, but I think the seme would've rembered I think he was probably just someone in the audience and he's been watching so that he could finally blackmail him into fucking... or he just just saw him got horny and took the opportunity
Guessing they used to fight each other and uke used to beat the seme in competitions and that’s where he got his love for seeing the seme in pain from maybe?
