I love when the cats have bowties. The epitome of classy.
You're right. Classy cat + classy bowtie = ultimate class. It's simple math. Unfortunately my cats disagree and think it's ultimate dishonour and slow death.
Seriously, it feels comedic how much of a dick he is. Like they had to have seen his true nature, at least a little .
If I were to take this seriously, I'd say love blinds. That they might have seen some signs, but they closed their eyes to it, tried to justify them in a way that makes him completely innocent. Daichi specially seems the kind to absolve his lover of all faults.
But, honestly, this seems like a fun read, but not some incredibly realistic story. Ran is a caricature and their situation an exaggeration for entertainment value. So I can accept that maybe they didn't see it at all. But they might still reflect about the missed signs in future chapters.
