....great the fucking ex has to ruin it. let me guess...he tries to hide mizuhara in his room and invites his ex in asking her what is she here for. She either drops some type of confession or talks shit about mizuhara. Probably the latter. MC will interrupt the ex and say how much he loves Mizuhara and Mizuhara will be hearing this for the first time with her heart going doki doki. Then ex will declare something to get back at MC and storm out the room. MC gets embarrassed, and their relationship will finally escalate...to holding hands. As they fall asleep the ex gets run over by truck-san who's been crossing over through many isekais.
