Can't talk on the main thread because it will be considered a spoiler!
God, he is so cute! When Si Tu Mo's mother came to visit, Gu Wei Yi went along with everything she said and agreed to everything, no matter how uncomfortable he was, but the only thing he spoke out against was when she said Si Tu Mo should concentrate on Accounting. He stood up for Si Tu Mo!! I am pretty sure Si Tu Mo fell for him deeper because of that. Such a sharp contrast from that fickle-minded, immature asshole.
And when Si Tu Mo rejected the 2nd lead, Gu Wei Yi was soooo happy it was so endearing.
And when they went shopping together and Si Tu Mo fed him that sweet when he initially refused to eat it because he doesn't like sweet stuff. He legit had heart eyes!!
I watched 10 episodes in one go last night and it has been so overwhelming because Gu Wei Yi is so so so cute that I needed to let this out of my system. XD
