When they first met:
"An'an, he's going to be your little brother from now on."
"My name is Su Yi'an. What's yours?"
"..."
"I'll be your big brother from now on."
"..."
"I'll protect you, so don't worry!" The little boy patted his chest, firm and gentle.
Now:
"Big brother, let's take a bath together~"
"..."
"Big brother, where's my hug before you go out?"
"..."
"Big brother, where's my goodnight kiss?"
"..."
After Su Yi'an learns Lele's identity,
After Su Yi'an turns evil for Lele,
He has only one goal: to protect his little brother.
Even if it means joining forces with demons and evil gods,
Even if it means making enemies of the whole world,
He is willing.
"Since you dared to try to hurt my Lele, you'd better be ready to face death."
"It is your honor to die for Lele."
