Substitute Marriage / (DUBBED) Bride by Substitute, Love by Fate

"The girl took her elder sister’s place to marry a wealthy heir, as her sister refused the political marriage. The two became legal strangers living under the same roof. When she started an internship at a magazine, she was unexpectedly assigned to interview her own husband. Flustered, she tried to avoid him and claimed to be single in public. Meanwhile, consumed by jealousy, he made his claim over her. Love is not just a fleeting infatuation. It is when we let down our guards, yet still choose each other firmly and exclusively."
