Thirty years old is the midfield whistle of life. Some people are trapped in the regrets of the past, some are stuck and confused in the workplace, and some are wrapped in armor and dare not go to love. Wutongli, this old community with hidden fireworks and scars, has become a place of redemption for the three women.
Lin Wei (deputy director of the subdistrict office) smoothes the edges of her ideals in trivial daily life. The breakup eight years ago is a scar that has not healed in her heart. The return of her old love Cheng Yu (a planner) allows her to learn to reconcile with regrets and stand side by side with her lover.
Su Qing (credit manager) uses risk control models to measure everything, but cannot understand the emotions in her heart. She made a small statement and guarded it silently for eight years, breaking her rational barriers and letting her understand that love goes in both directions.
Zhou Xiao (a cardiologist) uses professional armor to isolate herself from vulnerability. The estrangement from her father and doubts about her self-worth make her internal. The appearance of gentle teacher Lu Chen melts her ice and teaches her to rely on and be loved.
Three couples in their 30s and a man and a woman intertwined in the daily life of Wutong. There were struggles in the workplace, emotional temptations, misunderstandings and reconciliations, and sharing weal and woe. They repaired the old community, and also repaired the broken themselves. It turns out that healing at thirty never heals by oneself, but has people walking with them, and encounters warmth and hope in the world of fireworks.
