Beast!Dazai POV. Arahabaki and chuuya are sharing one body, but Arahabaki knows the future. Ats fist he hesitated to bring it up but he knew Dazai will die and he felt this obsession to reunite Chuuya with Chuuya's 'other half' before then. Chuuya has no idea but still feels a rather passionate love that mingles with hatred and obsession for his boss, Dazai.
