Wtf?

param literally said "whatever"

That's not yes. He only gave in because Mr Han kept pushing him, and he has feelings for him. He rejected him multiple times.

if someone is not interested to have sex with someone they will never give in to them. param is at fault as well. mr han is jerk from the beginning, but after knowing mr han's true nature param still gave him consent. that push wasn't enough though. if you read the raw you can see when mr han came to ask him something param literally pushed him away. that kind of push was needed here. they were in public param had lots of time to escape from the situation but he didn't

You shouldn't blame the victim in these types of situations. It's not his fualt that he can't push away the person he likes. It's called manipulation, his actions are being controlled.

I don't think he is a victim here. he totally wanted it. if he didn't he totally said no.

He did say no. He only gave in because he was reminded that he has feelings for Mr Han. Mr Han doesn't know boundaries, don't blame Param because he was manipulated.
