I hope in the coming episodes, everyone will be less harsh on Kawi just because he doesn't reciprocate Pisaeng's feelings. Please do not expect him to suddenly move on from Pear. Remember, he has been in love with Pear for more than a decade. So, we can't just force him to change his feelings. Also, I am so proud of Kawi, instead of procrastinating, he told Pear how he feels, made up with Max and is also trying to take care of his father more. He is fixing his past self. He might not be the brightest star in the sky, but he is trying to do better, at least for himself.

Moreover, he tried not to hurt Pisaeng.
