The scene where Hirono and Yuuma both cried at the park is what made me believe they are really in love with each other. And I still believe that even after those 5 years their feelings still remain. So of course I'm rooting for them. I mean they are only 23 years old at the end of the story, whatever happened in the past, already happened. Whoever stood in their way to love is gone now, so please please be with each other again is what I''m praying.

Sorry if i offend you with my different view..
I think in that scene..
1. Hirono cried because he knew he lost his love, Yuuma and he had to give him up.
2. Yuuma, on the other hand, cried because he hurt Seono(he said even though Seono was clinging to the charm for safety, he did that, meaning hurt Seono) and also a part of it is because he knew when Hirono said take care of his brother that meant : Yuuma lost a friend. Maybe he did like him but not "love" not like how HIrono felt for him. If that was the case, he should have cried more painfully saying sorry in the rain.. That scene would have made me cry,too.
This is what I think after re-reading this story. If they had continued with plans to live together, maybe it would have become something more like "love"

People have different views and I'm in no way can say that mine is the right one, so don't mind.
I've re-read the story for around 5 times now in Japanese, so let me just say what I think.
Yuuma cried wasn't just because he hurt Seono. And also not because he knew he was going to lose a friend either. If you noticed, he cried way before Hirono asked him to take care of his brother. And if it doesn't seem that he cried hard enough for you then I don't know what to say. Also, the scene where both their parents sat together, I can guess what was going on. They for sure forced Yuuma to take responsibility against his will. He had no other choice left now. He was helpless there.
Btw, if the comment below is yours then let me say something there as well.
I see where everyone's coming from with their hate for Seono and how they don't want Hirono to end up with Yuuma heck even while reading this I was hoping a secret fiance would pop up that Hirono was hiding away lol but I think deep down after finding out Yuuma and Hirono like each other first (or at least what I got from it) I want them to end up together so they can have their happy ending and I don't see Seono as the villain even if he stole his brothers man... like he's an Omega! The brother even said he was bound to be attacked at least it was by Yuuma (that scene was heartfelt to!) ╥﹏╥ Idk some scenes I didn't understand so maybe I'm missing somthing but Seono I felt sorry for him.. I think he also liked Yuuma so When he said he hated being an Omega I felt like Maybe he's sorry for taking Yuuma unfairly but that was the only good thing that came out of it :( still think he should have worded his letter better ╮( ̄▽ ̄)╭
