Side note. Ig I could name the webtoon. Is called We Broke Up and is about this couple that is living in an apartment together and the landlord says they're required to stay an extra 6 months living there so they have to find ways to tolerate each other after having broken up. I'm guessing they fall back in love again
but since I cannot read it there's no way for me to know for sure

there's also a TV show version of it that I have not watched if you like kdramas and my synopsis sounds interesting to you.
