If any of yall don't understand what's happening because Cheongho was anxious all the time while yi rim was in the hospital he would continuously emit very tense pheromones and that made baby think that being close to his mama will cause his papa to be anxious and that is why he didn't want to be close to yi rim. Now that is feeling his Papa's calming pheromones, he finally accept his mama. Poor baby was just super tense.
