When Xu Chang'an couldn't find an answer, he would use himself as a reference.
Let's not mention conjecturing why the girl would fall for him, it's difficult enough for him to figure out what made him admire her...
Was it their first meeting, thinking he had encountered a celestial being as stunning as the starry sky?
Or after getting to know her, being enchanted by her Nine Heavens Immortal-like beauty?
Perhaps it was knowing the threefold cuteness hidden beneath her cold demeanor that made his heart race.
The reasons that moved his heart are as countless as the stars, so Xu Chang'an didn't know when he was moved, perhaps it was… love at first sight?
Anyway, ever since he opened his eyes and saw the girl, knowing she saved him, he couldn't suppress the thought of wanting to stay by her side.
But Xu Chang'an was well aware that such feelings were admiration.
Then when did this admiration transform into affection…
That's worth discussing.
