A heart full of sincerity had ultimately been given to the wrong person...
Other than his own people, when had Sogo Doma ever been so considerate of anyone else? Yet Shizuka Hiratsuka still thought there was something more to his words, that he was being subtle...
Did Sogo Doma look like someone capable of subtlety? If he were subtle, he would never have come up with nicknames like "Plain as Plain Can Be" Yukino and "Everything on Display" Eriri.
That was right—he really was unhappy about Shizuka Hiratsuka pushing Masuzu Natsukawa into the Service Club. That little white-haired girl had set her sights on him. If this had been his temperament back in the early 2000s, he would have fucking gone along with it and PUA'd that little white-haired girl into a complete idiot!
It couldn't be helped. That little white-haired girl had handed him such a huge weakness. The key to PUA was destroying the other person's confidence. All Sogo Doma had to do was latch onto the fake-couple issue and keep brainwashing her: "If it weren't for you, I would've already done this or that..."
Then he could emphasize his own importance: "I'm the only one who'd put up with you. Who else would go crazy with you?"
If a few suspected love rivals showed up after that... In short, destroy her confidence, make her feel guilty, then constantly stress his own importance. For someone like Sogo Doma, who was well versed in psychology, it was as easy as eating and drinking. He had even taught that dumpling girl before:
"If someone keeps telling you that you can't do this and that you're wrong for that, don't be afraid. They're just trash. Take them out. Once you take them out, you'll find that the world is still beautiful."
