Why he was acting weird when he met Nam Joo’s mom…
Because that was his mom in the previous book
Why he never bonded with Kyung after he woke up like he did with Dan Oh and Do Hwa but was avoiding him, because in the precious book Kyung’s character and Squid’s character fucking hated each other.
Why the Squid was mad Dan Oh and Haru were falling in love, because it was their love that caused Dan Oh to die for Haru by Kyung in the previous book leaving them all with the guilt of her death.
Which also explains why when the Squid found out Kyung was awake, he said he doesn’t know where this story is going anymore because Kyung being awake makes it all more unpredictable.
