If you like light, fluffy, romantic shows where the lead couple isn't dragged down by lack of communication, etc, Love O2O is a good show. While there are obviously some conflicts in both shows (wouldn't be a drama if there wasn't), the lead pair isn't hindered by it. The plots are not similar at all but if you enjoyed Touch Your Heart, you will definitely enjoy Love O2O. The lead pair's chemistry is off the charts.

Both are super interesting and the plot has many twists and turns.
Both are lowkey on the romance if that is what you prefer.
Both are intertwined with betrayal and deceiving people
Both have the concept of a “game” in them.
Villain characters in both were really good.
