18 Outra Vez (2020)

If you liked the character developments, the unexpected surprises, the life lessons, the realistic set with fantasy (I know it's contradictory lol), the cute and fluffy youth romance, and the going back in time type of coming-of-age dramas, I Don't Want To Be Friends With you is perfect for you! You also might need a box of tissue :')

both of them have body change element, married couple, husband has the same age as their son, age difference

both leads end up going to their past selves. in 18 again, the male lead is transported to his past body and lives in the present day. In Reset Life, the female lead is transported to the past and lives in the past life.

Both are great dramas about second chances and having a second shot at life
