Four generations in the military, four families bound by old ties, raised together in the same compound.
Su Yan comes from the most decorated military family. Cool, composed, rational, and restrained, she's a top-ranked science prodigy.
Lu Shiyan comes from a distinguished military family with an ironclad tradition. Proud, sharp, and supremely disciplined, he's the only rival who's stood alongside her for years.
They've been classmates for twelve years. They understand each other better than anyone, and have secretly loved each other for over a decade.
The military values carved into their bones, along with their clearheaded restraint, outweigh the stirrings of youthful love.
With their weighty family backgrounds and bright futures, they don't dare speak lightly of romance. They can only hide their preference for one another within the bounds of propriety, staying together year after year and standing side by side as childhood friends.
There's another pair of bickering rivals in their compound.
The passionate, spirited humanities prodigy Xu Anxia faces off against Jiang Zexu, a sharp-tongued, laid-back, secretly brilliant student.
They've been arguing since childhood, exchanging barbs and loving each other through their fights. They may constantly complain about one another, but each favors the other above all. Neither dares to expose their ambiguous feelings, afraid of losing the bond they've shared for years.
The phoenix trees flourish in the height of summer during their senior year, while the young hearts' feelings lie buried in silence.
Four hidden affections: two buried in restraint, two caught in a tug-of-war of tentative advances.
Once, they kept their love secret and anonymous.
When their futures are settled and summer draws to a close,
they will finally break free of their restraints and let the love they've cherished for years shine openly, no longer anonymous.
Theme: Young people from military families with generations of friendship hide their feelings and keep to propriety as they grow side by side through youth, until the secrets of their hearts are finally revealed in the bright light of summer.
