Si An

Si an is your typical Asian jokester in class or at work. Whenever he opens his mouth, you will tend to laugh. He might occasionally reuse his joke, but it is useful to have him around.

When you have a Si An, he will stick by your side through thick and thin. So, cherish him.

Under his facade, his insides are burning down. He might have had a history of people laughing at him because of his name. On days when he feels sian, it is easy to cheer him up. He might even make a joke that might make you laugh.

Si An is a wonderful person and once you really lose him, it's quite hard to get him back. Cherish your time with a Si An.

"hahaha, he's so funny,"
"yeah, ikr? such a si an!"
