Similarities
- big families (4 children - 1 oldest son and 3 daughters)
- conflicts of in-laws and marriage life
- mothers are frenemies
- fathers have rough and secret pasts
- ups and downs of marriages (featuring break-ups and reconciliation)
- both fathers I believe have chicken shops
- brother in-laws (established ones) are very cute
- clingy mother in-laws
- battles against miscarriages

Differences
Once Again focuses on love between parents and married couples, specifically married couples, and its ups and downs whereas My Father is Strange seems to focus on the love of parents and the lengths they go through. I also think that Once Again tackles thing quite heartedly and focuses on starting all over again (hence the title) where as My Father is Strange may seem light but in relation to its title, there is a bigger, and deeper plot from the everyday struggles of the family.

Personal opinion:
I personally found myself particularly interested in the third children's lives. Both families' chemistry are insanely amazing but there seems to be more sibling moments on My Father is Strange as I feel like Once Again focuses heavily on married life. Both dramas are very slice-of-life and comedic and I wasn't able to stop watching them once I started.

both touches different perspectives on how people live their lives
handmade love focuses on regaining confidence through clothes whereas move to heaven focuses on moving on through keeping sentimental values
in a way they look at their clients' lives at a glance and provide their service towards them
both are very heartwarming and non-cliche as both deals with real life circumstances
the cinematography for both dramas are is also perfect !! just the overall lessons in both dramas are very eye-opening and heartwarming
