The main character, who is initially in love with someone else, after a sudden downfall/demise, gets to go back in the time with a chance of altering and mending things while falling for someone completely different in both the series.
Even though their plots are different, both ABM and SKL had kinda similar vibe in terms of cohabitation trope and a naive yet funny male lead who's completely dependent on the female lead as he is unfamiliar with the outside world. In ABM the ML is an angel with lost powers while in SKL, the ML is a rich heir with lost memories.
