Mucha and Yesijue were childhood sweethearts from a wealthy family, but they parted ways due to the sudden death of their common white moonlight, the sunny boy Ji Yun. Reunited five years later, the two people who were forced to marry were alienated on the surface, but undercurrents surged. Mucha accidentally broke into Ye Sijue's forbidden flower room and found the garden full of blue irises and Ji Yun's relics, tearing apart a corner of the dust-laden truth. As the investigation deepened, she was shocked to realize that Ji Yun's death was no accident, and that beneath the old scars on Yesijue's chest was a protective oath that was heavier than love.
"Ji Yun finally asked me to protect you." On a rainy night, Ye Sijue finally handed over the edited surveillance video, "But what I fear most is that you will be trapped in that summer forever." When the lie peels off, Mucha must find the painfully tampered truth in the memory maze - some people leave in order for another person to learn to love bravely.
(Youth pain + healing and redemption + suspenseful twist, an ultimate sadomasochism about growth and farewell)
