A rare yaoi manga where the seme, despite wanting the uke terribly, actually acknowledges forced sex = rape = bad, and continues to ask for consent. The actual premise is funny, with the uke receiving dreams of the future and seeing himself with this guy and refusing to accept it. I loved the two families and the glimpse into the future. If you actually want to see their first time together, it's ch 7 in Aruji No Oose No Mama Ni.
Overall, if you don't mind super tsundere ukes and like fated lovers and devoted semes, this is a great manga.
