Yeah, it ends there, each episode ends with the people coupling off. Next ep starts with different celebs (but some celebs play every week), and sometimes different games! It's not a drama so you can let your imagination stretch for what happens after, haha. Guess they all have to go through a breakup to pair with a new person next ep though, LOOOOOOOL.
And HANKYUNGGG <33 I love the Han Kyung + Ayumi couple

Both can't speak Korean properly it's so cute <3 Yeahh~
Season 3 is good. I haven't really watched other seasons of Love Letter.
