The premise was interesting, but the overarching plot was beyond stupid, a classic case of "I know how I want it to end, let's just stuff random things to make it happen. Let's also add some useless fabricated drama."
Also, everyone talking to Tamago was basically "Oh, so you are depressed about the death of your friend you may or may not be responsible with? Can't you just... not? It's inconveniencing us..."
