"I'm available!"
If his little sister asks him, he would be available even if he wasn't!
If his little sister was asking if he was free, she definitely is trying to ask him out.
He was a little excited at the prospect of going out with his little sister.
"Alright then," Jiang Yu continued. "Accompany while I go shopping. I need to buy some clothes."
Jiang Ze Yu was stunned. "Accompany you… Shopping?"
He has never been shopping with a girl before…
"Yes, would that be a problem?"
"No… No problem at all!"
Why would there be a problem? There shouldn't be any problem!
Jiang Ze Yu felt he had not been sincere enough in his answer and quickly added, "Little Sister, don't worry. I will definitely be available! What time shall we meet on Sunday?"
"Nine o'clock."
"Okay Little Sister. Where should we meet? Do you need me to pick you up?"
Jiang Yu paused. "Wait a moment."
