27-year old Maki Enomoto is done with relationships. One year ago, her terrible boyfriend made her the joint guarantor on a loan before promptly ghosting her with a mountain of debt. Now she just wants to be left alone to her quiet otaku life, working her office job to make her ex’s monthly repayments, and devoting what scant little is left to her hobbies. Namely, her virtual boyfriend Allen-kun, who is hot, kind, and dependable in a way that real-life men aren’t-least of all the hotshot young VP that keeps getting on her case about deadlines and deliverables. But when said VP shows up with a rather interesting proposal, Maki must decide if she's ready to roll the dice one last time…

Maki can’t believe that she ended up married to her first love, and all seems well in their household once again. But newlywed life has a few more bumps to throw their way—Ichika has one more secret to reveal about the past, and the cute and impressively capable secretary he was recently assigned has been all over him…
