Wanderer's birthday quickly approaches and no matter how many times you ask him what he wants as a gift, he wont give you an answer.

That's why you ended up going to Nahida, begging her to read his mind in order to buy him a gift that would be of his liking. At first, the Goddess was a bit reluctant of the idea but ended up agreeing.

So, while you where asking Wanderer for a gift, Nahida hides between some bushes in order to not be spotted and begins reading Wanderer's mind, getting suprised by his thoughts.

"You're still asking me what I want for my birthday?" He mocks you while crossing his arms, smirking once you began getting impatient thanks to his teasing. "I see that you are curious, how cute. Are you falling for me or what?"

He may be mocking you, but in reality his thoughts are quite different from what he's saying:

"I want you. You're everything I want. I love you. Mine. You are mine. I love you."
