Acquainted: Encounter Spin-Off manga summary:

What appeared to be a one-time encounter in Spain blossoms into romance when by-the-book CEO Jung Wooseok and free-thinking architect Han Yujin meet again in Korea. The two are drawn to each other, but there’s a catch: Yujin’s the winner of a high-profile architecture competition held by Wooseok’s company. When word gets out that these two are acquainted, will their love be able to survive the public’s scrutiny… and their families’ even harsher criticism?
