Ok so. The storyline was nice and sweet, not weird nor unkept, basically, it flowed well. It's a soft and simple plot and it reminded me of the drama, 时光与你都很甜 Beautiful Time With you. Both have very intelligent male leads, striving and hard-working female leads, and coincidentally they're deskmates. Personally, I despise romance dramas with a passion for their typical storyline and hardcore antagonist, who will literally go to the depths of the world just to try to be with a guy. Soft romances are an exception.
The cast/acting was okay. I wasn't cringing or exactly displeased. I believe for XMJ, she's a rookie actress? Her portrayal of the character wasn't terrible, but I'm not sure, it wasn't perfect. I didn't hate it. I found her character cute. CZY, I've watched some of his works before and his acting is obviously fairly better, being an actor. I enjoyed his character and his portrayal.
Music. I don't think I listened to it very deeply, but it was okay. I liked it. It was sweet.
Rewatch value. I would probably rewatch once or twice if I wasn't to feel bubbly inside. It was warming.
Overall, I enjoyed it. I binged watched it so, yeah.
