<human>: Can you succinctly summarize the text in 1-3 sentences?

Hello lovely people of Reddit! 

As the title says, I need your help with trying make things happen with my crush (let's call him Zack). 

Zack and I were casual acquaintances for a couple of years, but we ended up connecting this summer. We hang out a lot, and we text each other on (almost) daily basis. As our friendship grew, I realized that I have feelings for him. He is funny and incredibly considerate, and every text from him brings a smile on my face, so I really hope this goes in a positive direction. 

Both of us are very, very shy, so even dipping my toe in the water to test the temperature (so to speak) appears incredibly daunting to me. Also, I am terrified that I will end up making a fool of myself. He has made a lot of sweet gestures, but I still have a hard time deciding if he did that because he values me as a friend, or because there may be something deeper. But I have decided to gift him a book on something he is very passionate about, and I would love to include a note in the book.

Herein lies my problem. I have no idea what to write in the note, and how to express my feelings for him, without being too sappy or cheesy (or scary). On the other hand I can't even just write "Hey Zack! Thanks for an amazing summer!".

So, wonderful people of reddit, I have come to ask you for help. Would you please help me write a short and sweet note to Zack which expresses my appreciation for all the lovely gestures he has done for me, and the time we spent together and wishes him well for the future without being too sappy or cheesy? 

Thank you so much! 

(Also, I hope its not too much to ask, but if you have any interesting facts about soccer, please let me know! :) )
