While watching this drama, I realized a lot of things that I already know. Sometimes you don't need to learn something new, you just need to be reminded of the lessons you have already learned. There are precious things in life. We can't deny that time is one of the best treasures we have yet the most taken for granted. We always think that there are next time or there are still time but truth to be told, we have to enjoy it while it lasted.

Here, you will be reminded of the things you did in the past or the memories you never have. Above all, too late is just fine. As long as you take action right after your realizations, you're good.

I am so happy that I watched Sweet Home first before 18 Again. Lee Do Hyun's performance in both series is phenomenal.
