Yu Yan woke up as usual that day -Late! . When she lived alone, she won't wake up for the whole day even if she was hungry, unless of course for work. Her motto was : Work hard to sleep hard.
After she met Li Jun, Her routine subconsciously changed slowly. Now the latest was 9 am... but it was still very late by Li Jun's standard- he always woke up at 5 am before he met her.
