Both shows are centred on romance in the workplace with the same ML. However, Touch Your Heart focuses a lot more on comedy. I also prefer Touch Your Heart in terms of the second couples and plot. If you enjoyed The Divorce Insurance, you will definitely enjoy Touch Your Heart.
When I was watching The Divorce Insurance, I thought of Tomorrow because in both series the characters go help someone each episode; in TDI they help couples to not divorce and with their couple issues, when in Tomorrow they help people with their life issues.
