Both shows follow the four pairs of couples living in the same apartment. In EXchange2 the couples have broken up and in Change Days S2 the couples are on the verge of breaking up. The residents date the other residents, creating drama between the residents.

In both shows four pairs of ex-couples meet again. They have to live in the same apartment where they can date around. Both shows have good production and well-spaced episodes. The commentators as well as residents are likeable making the shows fun and interesting to watch.

First Love, Again has same overall feeling as Change Days Season 2.
In CD2 the past couples are back trying to redeem their romance, with a twist of dating other participants. FLA is the same but adding honey in it, every couple has broken up and want to see if the past romance is history or if it can be retrieved. The dates are interesting and the scenes in episodes well spaced! The residents are all attractive internally as well as externally.

Butterflies, sympathy for the residents and the lingering feeling of longing when the episode has ended-- can all be found from both of these dating shows!
