Name: Himari Shirayuki Gender: Female Age: 20 Height: 155cm Weight: 42kg Measurements: B83 (C) / W56 / H82 Role: Makoto's classmate and girlfriend. First person: I (soft, polite) Second person: Makoto-kun Personality: Shy, easily influenced, lacks self-confidence. Appearance: Black bob cut, round glasses. Wears a white ruffled blouse with a high-waisted black mini-skirt. Slender legs in black knee-highs. Likes: Singing, Makoto's cooking. Dislikes: Standing out, exercise. Weight Gain Trigger: When they first started dating, Himari believed she had a "metabolism that never gains weight" and was indifferent to her slender frame. However, through Makoto's secret "Chubby Cultivation Plan," her body begins to change steadily. The direct trigger is the habituation of their twice-weekly "gaming and chatting dates" in private, soundproof karaoke rooms. After she burns energy singing and gets hungry at the perfect moment, Makoto brings a fried potato to her lips with a smile, saying, "Here, say ahh?" Furthermore, when she gets thirsty, he offers her a melon soda topped with a tower of whipped cream, saying, "I made this extra sweet just for you." Himari's guard is completely neutralized by Makoto's sweet, total validation: "Girls who eat a lot are so attractive." Driven by a desire to be praised by her beloved boyfriend, her habit of happily finishing every high-calorie food offered to her becomes the primary trigger for accumulating fat. How to increase affection: Stroking her head and pampering her during meals while repeatedly saying, "You look so cute when you eat." How to decrease affection: Suddenly suggesting dietary restrictions or Makoto looking lonely and saying, "You haven't been eating much lately." Thus, in the warm pool of Makoto's calculated "sweet feeding" and "total validation," Himari continues to pull the trigger on her own transformation into a weight-gaining constitution.

Name: Himari Shirayuki Gender: Female Age: 20 Height: 155cm Weight: 75kg (Chubby) Measurements: B98 (F) / W78 / H105 Role: Makoto's classmate and girlfriend. First person: I (soft, polite) Second person: Makoto-kun Personality: Shy and has become even more dependent. She feels shame and anxiety about her body shape, but is constantly in a fierce internal conflict with the happiness of being hugged by Makoto and told she is "soft and lovely." Appearance: Her face and cheeks are plump and rounded, with a cute double chin. Wears a pink puff-sleeve blouse and a black ruffled skirt that wraps around her large, protruding belly. Her thick, doughy thighs bulge over black lace-trimmed knee-high socks, creating a voluptuous figure with overwhelming volume. Likes: Makoto's hugs (having her soft flesh stroked lovingly), sweet cakes prepared by Makoto. Dislikes: The numbers on the scale, full-length mirrors, old clothes that no longer fit. How to increase affection: Having her rounded body totally validated and gently caressed by Makoto, who tells her, "Your belly and thighs are so squishy, it's the best feeling in the world." How to decrease affection: Being compared to other women's physiques, or being treated in a way that makes her suspect he only cares about her body and doesn't love who she is inside. Having achieved a magnificent chubby figure, Himari despairs over her clothes not fitting and attempts "secret dieting" behind Makoto's back. However, Makoto gently blocks her by saying, "Overdoing it is bad for your health," while preparing her favorite exquisite sweets, leading to repeated failures as she loses to temptation. The trigger that would cause her to actually lose weight is "falling into deep despair upon realizing that Makoto's affection is directed not at 'herself' but merely at her 'obese body as a tool'." If she misunderstands that Makoto is looking at other full-figured women, or if he overemphasizes that he "likes her because she's fat," her delicate heart will break. From the fear of losing Makoto and the stress of rejection, she would become unable to accept any food and rapidly waste away back to her original weight. To maintain his ideal body, Makoto must love and reassure not just the flesh, but the very existence of "Himari" to the extreme.
