Si-ying (Sung Yuhua) is a university freshman who works at a cafe. Here, she met A Bu-si (Megan Lai), a professional coffee maker who can make any type of coffee drinks according to a customer's order, the shop's proprietress (Vivian Chow) who is often quiet and alone, seated at a corner of her cafe most of the time, as well as Ze-Yu (Marcus Chang).

One day, Senior A-Tuo (Bruce), a senior of Si-ying's who's pretty legendary in the university, came to the coffee shop with his friends where he met a reportedly lesbian who stole his girlfriend - A bu-si, by coincidence. As the friends kept teasing A-Tuo, Si-ying, full of helping and justice heart, helped A-Tuo out of the difficult situation. The two of them eventually became friends after several encounters. Senior A-Tuo is an optimistic person with a happy-go-lucky personality. Besides working part-time at a roadside stall, he also works for Bao (Lee Luo), who was a movie director and now a mediator for gangs, as a cook at his restaurant. There, he got to know Aunt Jin-dao, Bao's wife, (Pauline Lan), and learned to cook a noodle dish from her. After Bao and his wife fell out due to a petty argument, she started up her own dry-cleaning shop which was where Si-ying first met with Aunt Jin-Dao.

Started out as acquaintances, Si-ying and A-Tuo become good friends with each other after hanging out for some time. A-Tuo started having feelings for Si-ying, but Si-ying only treated him as a friend whom she can confess any thinking in her heart openly, as she likes Ze-Yu. Later, Senior A-Tuo went backpacking overseas. It was during this period that Si-Ying realised that A-Tuo is the one whom she has been waiting for all along.
