This is a story about life.

From the small things, to the big events, it's all shown in a simple way, just as it is. Sometimes slow, sometimes incredibly fast, and it's somehow relatable, because it's about emotions and concerns we all experience in some way, at some time in our lives.
Sadness, insecurities, hardships, fear, longing, regret, foolishness, maturity, growth, joy, nostalgia, comfort, gratitude.

I think this is a drama that teaches something important: find meaning in the small things in life. Every caring word and act has meaning and they have more value that what we may think for a moment.
It also teaches that family is not only the one of blood, family is the people who know you, stay with you and care for you no matter what.
I really loved the heartwarming friendship and incredible bonds between people shown in this drama, it was a joy to see, and i loved every character, whom I grew fond of.
Also, the cast for this drama was truly amazing.

Anyway, this show conveyed to me something precious: live to the fullest, cry sometimes, don't miss too many chances, be brave, enjoy life and say "I love you" to your important persons.
Finally, it reminded me, once again, that friendship is one of the greatest treasures in life.
