It is a similar feeling, they grow up together and share feelings. "When we were young" is a bit more romantic and "Go Ahead" is more family centric, but both are really good.
The tempo, the love story and the dynamic is the similar. Love that comes back again in some way. They reminded me a lot of each other.
It is similar in the way that they are both about family a long running drama, where you follow both the older and younger generation. Family constellation and love and relationship.
