Disappointing ending

This was a very cute and comforting drama. I liked the cast and the characters. The supporting characters were great.
Everything was good but the ending vas extremely disappointing. The relationship between Cha Heon and Shin Soli as adults felt rushed. I wish they wrapped up their story instead of spending 17 minutes (out of 25) retelling their love story but from his perspective. It didn't add anything new and just wasted time. Even the second couple got a better wrap up that the main couple.
