In case anyone wants spoilers, i found the link to the spoiler forum of the novel

You should read the spoilers from the link that Zinan shared. I was referring to when the ML ignored MC during his father’s funeral. He didn’t return MC’s communications, which impacted MC’s self worth for weeks. MC had to metaphorically chase ML, then ML proposes without much of an apology. Not happy how it went.
I think the same thought the uke was scary at first but then realised that he was cute?
I also remember that the author has the cutest chibi’s of the characters (▰˘◡˘▰)

Is this TGCF donghua countdown real?
