Qi Wang Zhi is actually really good at acting like the victim. I mean don't forget that it was him who kidnaped Yu Sheng and turned him into an Omega, so that he'd stay by his side. And it is also Qi Wang Zhi who ignores the feelings of Yu Sheng (the fact that he already has someone he loves) and tries to push his own feelings onto him (getting the tattoo etc.). Yu Sheng had told Qi Wang Zhi a lot of times that he only sees him as a brother, like this there is nothing wrong with Yu Sheng being worried about him, when he is in bad condition. Also Yu Sheng realised that Qi Wang Zhi is unhealthily obsessed with him, so with not being around him, he only tried to get rid of that obsession.
I've got no patience for Yu Sheng at all. He really has the balls to constantly disregard Qi Wang Zhi and trample all over his feelings, then turn around and cry about how he "cares" about Qi Wang Zhi. Shut the fuck up, no you don't.
