Oh Sehun is a normal teenager like anyone else. He goes to school, hangs out with his friends and might like being home a little too much some weekends. But one day one of his friends takes him to one of the local coffee shops - Sunflower Cafe -  and there he sees a person who manages to take his breath away.

Characters: 

Oh Sehun
Main obviously. He's normally quiet and finds it difficult to open up to new people.
Some people might interpret his personality as rude and cold, that is the main reason why many chose not to interact with him. But two of the few people who haven't been affected of that are his best friends Huang Zi Tao and Kim Jong In.

Kim Jongin
One of Sehun's best friends. He is one year older than the other two of the group but doesn't really care about that. Jongin has a one-sided crush on Do Kyungsoo in his class and is constantly trying to be friends with him. 

Huang Zi Tao
One of the three best friends. Shares classes with Sehun. His life doesn't include much besides Wu Shu and his friends. Lives in a shared apartment with Lu Han and Do Kyungsoo, but that is something Sehun and Jongin don't know. Probably because Tao's too lazy to bother telling them. His relationship with Lu Han is very similar to one of brothers since they grew up together. Can be very oblivious to other persons feelings.

Lu Han
One of the baristas at Sunflower Cafe. He is normally a sweet and caring guy towards his friends and family, but sometimes he doubt himself and can take the blame for something he didn't cause. He is best friends with Zhang Yi Xing and has a brotherly relationship with Huang Zi Tao. Lu Han lives in an apartment shared with Tao and another guy from the latter's school - Do Kyungsoo.

Do Kyungsoo
A guy who's always alone and who reads whenever he gets the chance. Straight A student. Jongin's love interest, though Kyungsoo just find him annoying. He lives with Lu Han and Tao since his parents kicked him out when he told them that he's gay. His wall around himself became even thicker after that. 

Park Chanyeol and Byun Baekhyun
Two of Lu Han's co workers and a couple since high school. Two friends who're willing to give advice and cause you trouble at the same time. Chanyeol is surprisingly the most "mature" of the two, but Baekhyun has a confronting nature. Which means that he tend to confront problems right ahead and Chanyeol is the pretend everything's fine type. 

Zhang Yi Xing
Lu Han's best friend and also an employee of Sunflower Cafe. Sometimes really dumb things can come out of his mouth and sometimes Lu Han has to defend his friend. Yi Xing keeps telling himself that he is not in-love with a certain pastery chef named Kim Joonmyeon and that he is heteroual. It's Baekhyun's and Chanyeol's fault for making him think such thoughts.

Kim Joonmyeon
One of the two pastry chefs at Sunflower Cafe. He's hardworking and serious when it comes to baking and pastries, but when it comes to everything outside of that feild - he's completely lost. Has known for a while that he's feeling something for Yi Xing, but is patiently waiting for the other to make the first move.
 

Mr I have the longest list of names ever - is called Wu Fan Kris here
The boss of Sunflower Cafe. He is strict, but if any of his employees get into trouble he's always there to help.

I don't really know what to do with Chenchen and Baozi yet, but they'll appear in the story.
