They will get back together and flee with the baby, from that place. MC does get shot in the place of ML to prove his love for him but he gets saved. On the way, he keeps mumbling about all the things he has regretted doing while injured. He asked why ML didn't go see him on the stage and bring him flowers (as we see the imagination of MC in the first chapter) which made ML feel more guilty. ML finds out MC actually did send him letters but they got confiscated by the military and MC was later put into jail which we've already seen.
They start a new life at a new place. The girl working for MC as the baby's nanny gets married to ML's brother/friend (the long haired guy). ML got a huge collection of liquor and MC starts working as a dancer for another company. But ML found it agonizing to be apart from him all the time. It took away too much time from them which they could've spent being together. ML then buys a Camera that could film silent videos of MC dancing on the stage. Each of those cameras cost as much as a big mansion or a factory or something, considering the technological advancement of that time. But ML was more focused on saving MC's time and health.
ML finally got the chance of giving MC a bouquet of flower while he was dancing on the stage in the empty hallroom. They kiss on the stage and they romantic interaction gets unintentionally captured by the vintage camera and stays as a historical evidence of their love.
It's okay. Thank you. (●'◡'●)ノ
Oh, and the lady who was engaged to ML also gets her happy ending. She gets to marry someone who looks like ML aka her ideal type.
The ML and MC grew old together and there's actually more to the story but it might make you a bit sad and ruin the perfect happy ending you’ve just pictured just now.
Seriously can someone give any spoilers of the end theres been a recent update from the raws and I cant find anything about the rest of the novel T_T
