The romance is sort of the backstory and subtle. I actually really like how they develop every relationship in here.
I am in love with Benjamin, Mr. Hong Kong 2007! He is such a hunk!!! Drools. I also liked Onion too. I wanted him to at least end up with someone but that is another story in On Call 2. The least favorite character has to be Mandy's character, Mei Suet. I wanted to strangle her at times when she meddled with YK and CY. And her hatred toward her sister and biological father was just uncalled for. It's her mother who kept the secret. And it is not like her biological father and sister knew either. She was there to literally just piss me off LOL
