Nope. Kang Jinha is very respectful and allows Siwon to sleep on the bed while he sleeps on the floor. Though it gets too uncomfortable and he moves over to the bed later, but he doesn't try anything. Just goes to sleep. A nice change of pace to the usual, "Imma gonna rape you ain't that romantic?" bullshit I'm so used to seeing.
