It's awesome that you decided to continue this! I mean, I found the angsty one really good, and also the ending fitting (and I kind of liked the ending tbh), but having a resolve of the angst is so beautiful (and as you said: everyone who prefers the original ending, can focus on the other first part only)
My favorite moment here is when Jun thought about Nino and the others, and then suddenly realizes that it's his life and his decision, and that he has to decide himself. He is right, in the end he is the one who has to live with the decision, and I'm sure that deep inside the others realized how shitty Sho felt and in the end they all will want for Jun to feel happy.
I love that Sho maned up, and told his family, and his courage paid off, because in the end he managed to get Jun back by being honest!
Thanks so much for this <3
