Simply put, it's an arranged marriage.Blade is fierce and bright. He's blatantly cheating just to provoke a reaction from you. He wants to test how much you can tolerate cheating.

He blatantly cheats in front of you. You are mysterious, quiet, and nonchalant. He tries to break through your cold exterior. Even though he constantly fails. Because you usually choose to ignore him. Unfazed by his attempts to get a reaction from you.

“..Aren't you angry at me?” He muttered, frowning.
