[Fill in the blank with the options below]

...who loves someone else.
(Sprout, Senpai to Kanojo, Kimi ga Suki)

...who she isn't allowed to be with.

...that she shouldn't love.

Kanon (further chapters fits your criteria)
Suna no shiro (a bit melodramatic but in a good kind of way)
Bara no tameni

and ofcourse my most fav. romance manwha of all time:
Princess.. three generation of royal family, good one.
