Is it ok to say "I love you"?

New home, new job

| Quill, a 21 years old guy who used to live with his sister, Quinn, just moved into a small city to start his new job as a chemistry teacher in a high school. There, he met some new friends, some special students and met his first love.... |

"Hello? Quill?"

"Hi, Quinn, I thought it's quite late at your place by now, why are you calling me for?"

"Well, I heard that you just moved to the city to get a new job so I just wanted to know if everything's still fine"

"Thanks for caring, but I'm not a 17 years old kid that need you to worry about"

"Pftt... I really worry about you and that's how you treated me back? So a little sis is not allowed to care about her elder brother, huh"

"I didn't say that it's a bad thing! It's just that you should really go take a sleep now because it's very late and sleep late isn't good for your physical health, I'm still fine and I got everything under control. We can talk more tomorrow, I promise"

"...Fine, I'm heading to sleep, take good care of yourself, bye" Then, she hung up the phone.

Quill sighed, then put his phone back into his pocket, trying to focus on his new apartment's address. It'd be easier if he asks the local 'cause it seems like the apartment is hard to find, but Quill knows himself is a bit reserved... eh, it's alright, I could find myself around, at least... that's what he thinks.

After wandering for nearly 2 hours, Quill finally reached his destination-to his new home in a small apartment.
Places his luggage down, he let out a sigh, finally... that was quite a waste of time... ok, Move in the new place - done! Now to one of my most favorite thing to do, arranging my stuff! Yes, Quill really loves to keep his place tidy and clean, and he likes to organize his books the most, he could spend hours with them, sorted them by colors and by alphabetical. His luggage is a bit heavy 'cause Quill brought mostly books in his suitcase, along with some little personal stuffs that are necessary

Phew, settled in new home - done!
Now he has to check all the paper works to get ready for this new job as a teacher, then he'll also have to meet the principal and the others teachers as well, I hope I'll make a first good impression with them. 

After finishing his papers, Quill yawns, It's already 6p.m, I guess I'll eat out today since I haven't got anything to make dinner myself. Quill reaches for his coat then headed out side the apartment. When he was on his way to find a restaurant, Quill noticed there was a small book store in the corner of the solitary street near his living place, Oh! Can't believe there'd be a book store anywhere near here, I would love to visit it! But... dinner first, I'm hungry...
