I Just hate the fact that sand had to be an asshole😭😭
If you noticed in this episode Eiw's friendship with sand actually helped him loosen up and become a little more open and happy but the writers just had to do that😭😭 now like you said that might make him close up even more and he really shouldn't be doing that rn.
Yh cake definitely was jealous but I think it's just friendship jealousy for now.
I am so happy for the separation too😃😃
I really love this show!!!
