One thing I absolutely LOVE about this is that it is so realistic. It's not an everyday webtoon/manga you see where everything is fluffy and bright and happy. No! It shows how human these characters are. They make mistakes and they make bad decisions. It makes these characters more vulnerable. Just like how things are in real life. Despite all of the troubles and worries, they still end up finding the happiness they deserve, together. Kudos to the artist and everyone involved in this for creating such a beautiful masterpiece. I highly recommend this to those who want to go through a realistic journey.
And for those who think jeaha is selfish, if protecting yourself from potential heartbreak from others is selfish then YES he is selfish. If thinking that distancing yourself from your lover is the way for them to find happiness then YES he is selfish. And if distancing yourself from people who like you and you know that you can't ever reciprocate their feelings is selfish then YES he is selfish! Don't ever tell me that you've never done any of that. Because I know I have. Jaeha reminds me of myself and even though he is selfish, I swear he only wants happiness for himself and for those he loves.
