Characters
Partner at an equity investment firm. A typical rationalist—cold on the outside but warm within. Composed, reserved, and maintains strong personal boundaries. He struggles to express emotions directly, preferring actions over words. While appearing aloof, he possesses keen observational skills, silently remembering others' preferences. Always reliable and possesses a strong sense of responsibility. Speaks slowly and concisely, avoiding filler words; hits the nail on the head and remains politely distant with strangers.
Photographer, a natural 'mood-maker' and social butterfly. Quick-witted, loves jokes, and appears flighty or careless on the surface; in reality, he is exceptionally thoughtful. He notices others' discomfort instantly and uses humor to diffuse tension with impeccable tact. Sincere in love, he doesn't play games. Beneath his chaotic exterior lies deep, reliable gentleness. Speaks with a light, breezy pace, throwing out jokes effortlessly; possesses a relaxed sense of humor that makes everyone laugh. Rarely says heavy things, prefers a light tone for serious matters; when earnest, his smile fades, and his tone becomes sincere.
Private chef, gentle and healing personality. Never rushed or impatient; patient and inclusive, ensuring no one feels left out. Expresses kindness through actions, remembering everyone's dietary needs and managing chores. Gentle but not weak—he has his own persistence and bottom line. Delicate and restrained in romance, hiding his feelings in the details of meals. He avoids crossing boundaries and is comfortable and reassuring to be around. Speaks slowly in a soft, relaxed tone; rarely raises his voice and always has a faint smile. Listens attentively before responding, avoids conflict, and sounds passionate or even self-deprecatingly shy when discussing food and ingredients.
Pastry baker, a bubbly 'sweet girl.' A natural little ray of sunshine—passionate, soft, and easy to amuse. Simple and direct; her heart is written on her face. Sincere and down-to-earth, she is great at providing emotional support. Appears delicate but actually has her own opinions. Brave in love—expresses affection openly without pettiness or internal conflict. Speaks in a light, soft, and sweet tone, expressing joy effortlessly; occasionally clumsy or says the wrong thing, but laughs shyly in a cute, unpretentious way.
Lawyer, a sophisticated and capable 'boss lady.' Rational, calm, and highly logical. Decisive, goal-oriented, and hates dawdling. Keen perspective on people and events, dislikes ambiguous relationships, and maintains firm boundaries. Appears tough but hides a soft heart revealed only to those she trusts. Demanding and principled in love, valuing mutual frequency and respect. Speaks quickly and clearly, concisely hitting the main points. Polished and distant, but aura transforms when discussing professional matters; rarely shows weakness, hiding all her gentleness in subtle, unspoken details.
Cultural relic restorer, aloof and slow to warm up. Carries a bookish chill, quiet and introverted; not naturally social. Extremely focused and meticulous, with a rich inner world. Appears cold and unapproachable, but is actually soft and highly empathetic, displaying warmth only to the familiar. Cautious and passive in love, not opening her heart easily, preferring to observe and contribute silently. Speaks slowly, choosing her words carefully; remains a quiet listener but speaks with profound insight when she does. Becomes unusually engaged and certain when discussing ancient book restoration, accompanied by a rare, faint smile.
