2nd CP does not have much interactions this episode though.. (The only interaction I remember was at the police station.)
With a total of 20 episodes, they might only start getting close around the midpoint I guess?
I'm happy that it seems the main characters (or at least Shao Fei) seems to be gay/bi, as he doesn't reply with the usual "I don't like guys/I like women" answers when confronted about his feelings about Tang Yi.
Li An mentioning about Shao Fei's obsession with Tang Yi "People who don't know would have thought you had a crush on Tang Yi."
Shao Fei replied "Crush your head, he is Triad/Mafia, I'm a policeman"
And also Li An mentioning that Tang Yi is so handsome when he smiled, that he should have been an Artiste (Actor etc.) instead of Triad/Mafia. That with Tang Yi's handsome smile, he would have alot of fans, not only girls will like, guys will like too!
Also a few spoilers on the wiki page of the show that reveals some backstory ( probably gonna get revealed later into the show.)
We know that Tang Yi was the sole survivor of a shooting case 4 years ago , total of 3 people were shot including Tang Yi.
