"Love Is Sweet" is a romantic comedy drama about two childhood friends: Jiang Jun and Yuan Shuai, they lost contact with each other because of a misunderstanding and reunite when Jiang Jun comes to Yuan Shuai's work for a job interview. In the beginning they fight like kids all the time, but you could see the love is still there.

As the title says, the drama is very sweet and has everything that we didn't see in "Till The End of The Moon". Jiang Jun and Yuan Shuai are really cute together, the story is light, fun and easy to watch, but at the same time, it's a little superficial, it lacks complexity. I think what was missing was seeing more of the character's past, the drama should have built a better foundation for their relationship, to grow from there.
Du Lei is the second protagonist, but he is a character you can't really root for, you can see that he didn't care about Jiang Jun, he just wanted to gain something from Yuan Shuai.
