One of the best endings I have watched. I was so happy seeing them three go for the trip. The dark clouds moved away and its all happy and sunny. I liked how Sang tae and Mun yeong tried to give Gang tae a surprise. Their family t-shirt was so cute. They all got their happy faces back.. And the storybook was published . Sang tae was all tears showing his work to his mom.. that was so emotional. Beautiful ending.. It will remain as one of my favourite dramas forever.
