Long Yi had disappeared for three days. During these days, Ai Lin and the other girls had been accompanying Suolin. Suolin wasn't living in the secret chamber anymore; instead, she was in a regular dormitory. Her relationship with Ai Lin had grown very close, maybe because girls are more influenced by each other, or maybe because they had some things in common. Whatever the reason, Suolin prefers to call Ai Lin 'sister', which Ai Lin isn't used to since she is few years younger than Suolin according to their ages.
When Long Yi shows up with dark circles under his eyes, Ai Lin is helping Suolin to try on a pair of high-heeled boots.
"Confidence is something that comes from within! When Mr. Long said that putting on heels can give a girl confidence, you should try it too! It really works!" Ai Lin said while watching Suolin changing her shoes.
"Did I?" A puzzled Long Yi asked as he entered the room.
"Yes, you did!" Ai Lin nodded immediately.
