I watched My Love Eun Dong after I watched She was pretty. It gave me the same goosebumps as She Was Pretty gave me... My Love Eun Dong is really great, but soooo underrated! You should give both a go and you will fall in love with it instantly!
Both dramas have the lovers separated theme. Both have scenes about their younger years. Both have pining although the ML in My love Eundong is more proactive in chasing his love.
