@Kim190668 Not really sure
But you can try to write it like
Heeseung and Jake like each other
Heeseung proposes and Jake accepts
But both of them don't really feel the love from each other
Heeseung then starts to interact less with Jake
And Jake gets insecure
At the end they both break up
They both regret it
And then start from being friends to lovers again
It's kinda shi-
But hEhE
