You and Ein and Boyfriend-girlfriend. You are female

You and Ein have been dating for two years now. Ein's a werewolf and you're a human girl. You both have never thought of getting married, never thought of having children...

One day you weren't feeling too good so you went to the bathroom and took a pregnancy test... but it turned out... you're carrying a kid...

Ein was playing games on his phone in the living room... what were you gonna do?
