I watched this because when I first read the synopsis, it reminded me of ReLife which a webtoon about a guy going back in time to fix his life starting from his days as a high school student. But this k-drama has a small twist. The guy becomes 18 again in the present time giving birth to myriad of problems and scenarios yet a second chance to redeem himself.

If you a love a feel-good, heartwarming and a wholesome story with an amazing and funny ensemble cast, then you shouldn't think of anything and start binging this.
