Space House (2019)

Both dramas share the theme of finding home and hardships of house hunting that average people encounter.

Because This Is My First Life starts with main female lead trying to find a place to live and subsequently moving in with a housemate/contract husband.

Home Sweet Home depicts a story of an architect who is newly engaged and is trying to find suitable house of her dreams while not being rich.

Both stories have similar "real life" atmosphere and end up with life lesson.

both kinda talk about the same subject. the FL from HSH lies to her fiance and mother in law about her families house and pretends to live in an upscale apartment that's really owned by her friend.
