I might be misunderstanding something here, but i'll continue. How is it toxic for the boyfriend to fend off potential suitors for Jungyeon? Isn't it more toxic to actually find interest and slowly destroy someones relationship just cuz you feel its justified with your "love" for that person? Its like saying that wanting to be a mistress to someone whos married is justified as long as its out of love for that person.

I feel bad for him but you know what the other guy is toxic but anyway the uke chose him so I'm good about it but damn find him a new boyfriend I don't agree to let this end find him someone first
