[SEARCH] MANWHA

Hi, I'm looking for a manhwa where the protagonist moves to a new city after breaking up with his ex. He meets a girl through her sister, who is his landlady. During the story, his ex reappears, seemingly wanting to be with him on a whim. He ends up working at a gym in the city. I don't have any more details. It's not Excuse Me, This Is My Room or Touch to Unlock.

- Bonus: His best friend tells him she's pregnant, all orchestrated by his ex.
