Those who've read the novel

No

The story goes on much further.

Any idea if there's gonna be any side stories?

I hope so because it's really beautiful manhwa.i read it on a korean site and even after the story ended, there was a side story. But unfortunately, the side story wasn't on the site.valery and alexey go to Canada, they live together there, and Valery continues the ballet. The last episode is alexey goes to valery's ballet and they are very happy.(⌒▽⌒) even after this, the side story was still following me.even after this, it has a side story. I'm waiting for its english translation.

Hey, can you tell me if Valeri was in a relationship with Lianne during the 2 years he’s away from Aloysha? I really need to know

He didn't like Lianne at all and there was no relationship between them. When Alexei stays with valery in the hospital, he tells hkm to break off relations with lianne. he quickly breaks off relations with him.

Then Lianne tells valerie that maybe we'll see each other again later, but valerie tells him nooo, we won't see each other again. somehow, only valerie felt guilty about lianne. he had no other feelings for him.

Thank you for telling me. Somehow this part was weighing on me. It would have broken my heart for Alexei, if Valerie had been in a relationship with Lianne. This part wasn’t cleared in the manga.

you're welcome.I really love alexei too. I cried a lot during this novel, especially when valeri goes with lianne and alexei is left alone. Alexei decides to die.In the manhwa, the sadness of those moments is not shown.my heart broke there. But I'm glad it ended well.
