I say that because it'd be impossible with だって

Grammar Explanation: That said with だって

Takeo hopes to get into the same college as his girlfriend, Rinko. Going into a mock exam, he listed the top college Rinko is aiming for. However, the results came back saying it would be impossible for him to get into Rinko’s top choice.

Rinko tells Takeo she didn’t do well for that college either, so they should both aim for her second choice. Takeo asks if Rinko is okay with giving up on her top choice.

凛子(りんこ):: 「あはは　あれはいーのいーの」; “Ha ha, I'm okay with that.”; 「だってたけおくんは絶対(ぜったい)ムリだもん」; “I say thatbecause it'd be impossible for you to go, Takeo.”

Rinko’s first choice was a women’s college, making her boyfriend, Takeo, ineligible to attend.
