Honestly idk why some people felt that Phayu and Pai have a father son relationship. I mean I was almost at the verge of not watching this and making a good big mistake. Its just that once Rain said that Phayu was acting like "daddy" which soon he felt was better to replace with "hubby". And once Pai said "my son" while talking to Sky but clearly the situation he was in when he said that ...... no way he meant it in any other way than just a way of referring. Plus ig people should use their logic once before thinking that Phayu and Pai have a father son relationship, I mean srsly look at their age gap!!! Considering this it would mean Phayu was less than 4 when Rain was born!! Come on!!!
It was just so wonderful how this special ep showed that both Sky and Rain can be demanding sometimes as well. It showed the perfect balance between two people in a relationship and how valued it feels when your significant other tries to make up to you. It's also a very satisfying little ep. on how misunderstandings might lead to a bigger misunderstandings.
I HIGHLY RECOMMEND YOU TO WATCH IT (as long as you are ok with moderate 18+ content)
