Based on what i understand in this messy translation is that taeju wants eui hyun to stay with him not because of his debt so in short he likes him already but scared that eui hyun doesnt feel the same way and staying only because of his debt while eui hyun thinks lowly of himself as taeju's toy and hes scared that he is bored with him thats why he doesnt want to hook up (not knowing that taeju doesnt want to treat him like that anymore). Eui hyun is worried, if taeju leave them out there.. his brother's life will be miserable :(( so yah.. just communicate you two. -_- okay???
btw, feel free to correct me if i understand it wrong.. :((
