I must say that this story will be one of my favorites and let me list why is that:
1) Let's start with the MC, like the title suggest they meet by chance and constant chance encounters bind them together. Their story is the most beautiful and the purest. It will clean your taste buds. They meet, they slowly fall in love and they don't avoid or deny their feelings. There are parts of confusion but never did they try to run away from their own emotions. As their story progress there will be no major ups and downs and why is that? Because they show that good communication, trust and care is the key to the good and fulfilling relationship. The have moments of jealousy, they sulk from time to time, there are the moments of anger but this will never turn into a major misunderstanding (what I hate in many other dramas and novels) because they ask questions and they give answers, true and honest.
Really refreshing, a feast to the eyes and hearts <3 .
2) All the side characters and side couples have enough time to develop their feelings, we have full story of what, when how and why? There is no plot holes. But one of the best thing is that while the MC have quite of a smooth sailing the side couples don't have it that easy. We can see more problems here and I personally love this as I can have my beautiful and lovely story in the form of AePete but still I'm aware that world is not all flowers so we can meet this thorns in the other side stories. And yes they don't always end they way we hope for.
3) Physical side of the story doesn't end on just a kiss or holding hands but... on the other hand its not the most important thing in their lives. I love this balance between mental and physical needs.
4) Chemistry beetwen all the couples! Truly amazing!
5) When you'll finish this series you'll feel happy and satisfied but still hungry for more :) . This way I know that I'll watch this again and again and again probably as I wait for season 2 ;) .
