I haven't finished watching this drama yet but I had to stop and just begin my review. This has been one of the most wholesome and sweet Cdramas I have ever watched. I loved the pure innocence of our 5 main leads and although I love the main couple so much, I love that it focuses on all 5 of them, with their own little story ARCs and their friendship. I'm excited to see them go onto the next stage of their lives, and honestly I'm getting sad that I'm approaching the end of this drama. It has been a wonderful watch and I've been smiling ear to ear for the most part of it. It also has only been 2 days and yet I'm about to finish it just because I didn't ever want to stop watching. I wish they had more episodes instead of just the short, 30 minute, 24 episodes that we get. I'm going to miss this little group of friends dearly and I think I'll find myself rewatching this drama quite a few times after I'm done.

EDIT:
I finally finished the remaining episodes!!! OMG!! I'm squealing and I'm over the moon, this was such a beautiful, cute, and sweet little story. I loved seeing our wonderful ML slowly but surely open up episode after episode as our little sun persistently melted all that ice. I really enjoyed seeing their full journey, really my only complaint is that we didn't have more episodes of them in their college/adult life. I also adored our second couple, and I think it was just a shame that they got together so late in the drama. And of course, we can't forget about Guan Fang, our adorable, loveable 5th wheel. His care and dedication to his grandma was so nice to see. This was such a wholesome and heartwarming drama, I just finished it, yet I just want to be able to go back and watch it again for the first time.
Also fun fact: Falling Into Your Smile was probably my top Cdrama before this and I've rewatched that so many times already but it looks like When I Fly Towards You might take that top spot. It was a joy to watch the outgoing, dedicated Ai Jia turn into a shy, cold, introverted ML. Anyways, I think that's enough to be said about this drama. If you're on the fence, please watch it, I don't think you'll regret it! Bye for now!(:
