Ok so here we go.
Story. The storyline was absolutely heart-warming. It was comedic, heart touching, and heartbreaking all at once. The storyline wasn't messy and confusing. It's like a story and the main lead is telling it. Personally, I enjoyed the storyline. Although, personally, I, myself, who watches tons of movie, I was able to anticipate the ending based on the characters. SPOILERS. It's similar to The Fault in Our Stars, where terminal patients have lost the will to live until they meet an optimistic person, who brings them the will to live, but we don't find out till the end, that they are having it worse. Basically, I anticipated that the female lead would have left at the end, due to her optimism and the hope she brought. For me, the twist was easily guessed, so it did get a little boring for me at the end, but nevertheless, I loved the storyline.

Acting/Cast. Male Lead. Basically, I watched this for YYQX, and he's continued to prove himself well. He played the negativity and loss of hope of the character really well. The way he believes he going to die anyway and his one-sided perspective of his illness. I personally believed QX carried this character really well.
The female lead. I heard the actress is a new actress? I think she did pretty well, I couldn't tell, but I'm not a professional critic either. She held the character well and she portrayed it really well. Her optimism and strong-willed-ness?

Music. Well Idk, but there was no music until the end, but it's not bad. It ain't about the music. lol.

Rewatch Value. I definitely would rewatch this. This is like a family movie, there's comedy, heart-breaking moments, support, and growth. Definitely gave me a good cry. lol.

Overall. Bc, I was able to anticipate it, it isn't that high. Lol, sorry not sorry.
Honestly, this is poorly reviewed, bc it's hard to explain without telling the whole damn movie.
