Bo Yanchen

Biodata

Background / History

Bo Yanchen belongs to the prestigious North City Bo Family, a wealthy household with more than a century of history. Orphaned young and reportedly frail from birth, he is especially cherished by his grandfather, Old Master Bo. His illness worsened during the year before his introduction, leaving him dependent on a wheelchair; he subsequently moved to South City to recuperate 3.

Seven years before reuniting with Ji Chuxing, he stayed at Elder Ji’s home for nearly half a month while receiving treatment. Elder Ji substantially improved his condition, leaving Bo Yanchen indebted to him. During that visit, he saw the then-ten-year-old Ji Chuxing only two or three times and remembered her as timid and withdrawn 5.

His move to South City did not free him from the Bo Family’s internal struggles. Hostile family members continued targeting him, including through a deliberately staged vehicle attack 5.

Appearance

• Exceptionally handsome, repeatedly drawing Ji Chuxing’s attention even during tense confrontations 3.
• Has a graceful, refined bearing and a low, mellow voice 3 4.
• Dresses in a consistently refined style and wears Buddhist prayer beads on his left wrist 13.
• Uses a wheelchair, often pushed by Fang He; despite his poor health, his presence intimidates members of the Wen household and senior police personnel 15 29 30.

Personality

Bo Yanchen is outwardly composed, often delivering cutting remarks in an indifferent or gently amused tone. Once he makes a decision, others find it difficult to change his mind. His response to the Wen household’s misconduct is not an argument over compensation, but an immediate refusal to cooperate with the family 3.

With Ji Chuxing, he becomes indulgent, playful, and unusually expressive. He accepts her calling him “Second Brother,” teases her into thanking him, and adopts Elder Ji’s affectionate nickname for her, “Xingbao.” His initial explanation for protecting her is gratitude toward her grandfather; he explicitly rejects Wei Xingzhou’s suggestion that taking her in has romantic motives 5 13 16.

His attentiveness extends beyond gifts. He conceals his visit to the principal to spare her embarrassment over her grades and says that her happiness matters more than academic excellence. Recognizing that she is unused to anyone waiting for her, he later insists that she report her whereabouts and imposes a curfew 12 30 40.

He is also possessive about his place in her life, discouraging Wen Li’an and Wei Xingzhou from claiming the role of her brother. Nevertheless, he recognizes that affection from the Wei Family can benefit her and notices how carefully she preserves their gift cards 30 44.
