The Sacrifice's Last Guard (смешанная)

Up upon a balcony stood a boy about Lan WangJi's age, dressed in simple, white robes. His long, ink-coloured hair draped down his back, perfectly framing his figure. In the darkness, his silver eyes glowed, a clear indication of his identity as the rumoured sacrifice.
However, what really caught Lan WangJi’s eye was the tears that were streaming down his face as he looked up at the moon in the night sky.
 
Alternatively:
The GusuLan Sect is in charge of guarding the gods' chosen sacrifice until their twenty-second birthday. For years, Lan QiRen has held that duty. However, after he is called away on urgent clan business, Lan WangJi is asked to step in and guard the sacrifice for his last few months of life.
