no, that girl is the girlfriend of ml's brother, iirc she went there bc she wanted to leave side dishes for ml, the mom sending the side dishes for both brothers and bc the bro can't send it himself, so the gf helped to send it to ml place
I kinda forget whether the mom or dad who sent the side dishes to ml or brother, but they need to share that, so the brother's gf helped to get the side dishes, that's all I remember
Another one to my personal faves
