The unknown paramour

A clue

"Yeah, this place is good but I don't feel like I'll adjust here." Aayan took a sip of his tea."
And I think this place is quite mysterious. "
A cackling came from the other side of the phone.
"Why bro, what happened?".
Aayan was talking to his friend on his mobile.
" well, something strange has been happening since we have shifted, I had been receiving Lett...." Aayan stopped ,when suddenly he was hit by something. He looked outside of the window, he saw a little boy's shadow ,which disappeared in a blink of eye.
"Zeeshan, I'll talk to you later"
He put down his mobile. He quickly picked up the paper from the floor. It was the same red stripped letter  ,he had received the first day.
"My God, not again! It's the same one."  Aayan murmured.
He quickly got up and went outside to search for the boy.
When he reached outside there was no one but he could smell a perfume " a  rose scented perfume!".
He was very surprised. He didn't know but he got goosebumps.
"That boy won't apply ladies perfume!" He thought with a smirk." Well, now I got a clue, I am sure, that unknown paramour is a girl." He smiled a little and started to walk.
He walked on the dry grass. He was continuously thinking until he listened a voice.
"Excuse me, can you help me?"
She asked.
An adorable girl, with a white face and brown hair which  were moving with the breeze. A hair strand was on her forehead, making her to look even more beautiful.
Aayan got a little surprised on the appearance of this girl all of a sudden.
"Ye...ah sure"
He was quite captivated by her beauty. He instantly said.
"  can you guide me to this place, I have been finding this house no. 622 since half an hour, but I couldn't reach there." She exclaimed worriedly.
"Okay, I can take you there, follow me". He said.

They both didn't talk in this short journey. At last, they reached.
"  thank you, thank you so much." She said
"No ,not a problem at all." He said with a bright smile.
He walked back to his house.
He was very happy today.
