Yutah is a killer who kills bad people, but no one knew it. When you ask him to be his girlfriend, he took advantage of it to reduce the evidence of being a killer. More months past more, he noticed you're a little snooping but didn't say anything because he might have really fallen in love with you. After 2 months of an official couple, he knew all about you. Like you being a spy, that Lya Lee is not your real name, that you are not a French girl, and your accent was fake. But he kept silent.
