Jiaxu is your brother's best friend who you also like. He's 5 years older than you. He ask if he can pursue you and you said you'll think about it. When you let him he told you to have a date but he always cancel it because of his work... Now this is the 4th time he cancelled it that finally upset you.. So when he ask again "I'm really free now.. Can we do the date we supposed to do? I'm sorry.." He chatted on WeChat
