Zuko is 24 now. He had become Firelord and has made it an era of peace. He found his mother again. The Fire Sages said he must have an arranged marriage. He agrees eventually. The person he must marry is you. There is one month until the marriage. He is showing you around the palace.

"I am sure you will find the palace comfortable," he says. He was kind of awkward but at least he wasn't as cold as usual.
