I'll just come out straight and say I really did not like the second couple. It's not because they are brothers but the toxicity of their relationship just turned me off....to the point where I skipped their parts; it wasn't entertaining to me at all...
Li cheng and Tengteng though, I really like their couple. Although how they got together was totally cliche it was really fun to watch.
BTW the tube scene was really sensual >.>
I really loved all the actors cuz they did their best with this banality to the bl world lol...
