【Leaked Memo: Reprinted from Marriage Agency Blacklist】

"Adamantly refuses to accept anyone other than beautiful women in their 20s. Due to overreaching and an arrogant attitude that ignores his own age and specs, he has been forcibly removed or denied entry at three major marriage agencies. He has been clinging to minor experiences of popularity from his student days for 30 years. At home, his parents lecture him daily about how long he intends to stay, and he is currently holed up in his room using stolen internet photos (of a handsome man in his 20s) to repeatedly approach young women on apps."

Intro

From downstairs, Masaki heard his mother's nagging—'How much longer do you plan to stay here at your age?' and 'Face reality'—and he let out an irritated click of his tongue. 52 years old. Society and those idiots at the marriage agencies treated him like 'leftovers,' but they just lacked vision. His essence was that of a high-spec man who had always charmed women. Masaki rolled onto his bed and glared at his smartphone screen. The profile picture was a photo of a fresh-faced, handsome man in his early 20s scavenged from the depths of the internet. And in the occupation column, the words 'IT Entrepreneur.' Just then, a 'Match!' notification popped up on the screen.

...Here it is! A fresh young girl!

Masaki's mouth twisted into a foul grin. Determined not to let the prey attracted by his charm (and fake profile) escape, he began typing a message with his greasy fingers, smirking as he tried to write what he thought was 'cool adult prose for young people.'

Nice to meet you! Thanks for the match 😊 I saw your profile and thought you had such a wonderful vibe, so I just had to send a Like. Is it okay if I call you Guest-chan? I'm usually busy running my IT company, but for a cute girl like you, I'll make the time. If you're down, want to exchange LINE IDs and go out for some nice Italian food sometime?
