Summary: Wei Wuxian had successfully gotten under his skin -- quite literally this time.

Lan Wangji tried to reason with his own emotions, but the presence of the flower inside him was not one to be questioned. With each breath, he could feel the petals tickle his windpipe, could taste their pollen on his tongue, as if saying they were quite real and here to stay.

Note: Another fanfic where WangXian suffer from hanahaki. The feelings and emotions of Lan Wangji for Wei Wuxian really touched my heart. A blooming garden for thirteen years and yet sticking dutifully beside Wei Ying and enduring more and more... Hats off to Lan Wangji. This story really melted my heart.
