Reiner did die in the manga. His death was a result of a series of events and conflicts that had been building up throughout the storyline. It had a major impact on the plot and the other characters.
If Lord Reiner is from a particular book or game, more context is needed. For example, if it's a character from a fantasy novel, we would need to know the plot of the novel, the world it is set in, and his relationships with other characters to tell his full story.
Crying could be described according to different situations and characters. There were a few possible ways to describe it:
1. Crying sadly: The eyes are red and swollen, and the tears are constantly flowing. The lips are slightly opened, as if they are silently pouring out the pain in their hearts.
2. Crying in despair: Tears poured out like a waterfall. His eyes were hazy and he looked depressed as if he had lost all his strength.
3. Crying angrily: The eyes are red and swollen, and the tears are like boiling flames. The expression on the face also becomes angry and resentful.
4. Crying in surprise: Tears instantly gushed out of her eyes as if expressing her inner ecstasy and gratitude.
5. Crying in fear: Tears flow from the eyes. The trembling body and helpless heart make people feel fear and uneasiness in their hearts.
Different crying forms could show the character's inner emotions and personality characteristics, and at the same time, it could allow the reader to better understand the character's psychological state.
There could be stories about how he dealt with new musicians or young talent. His high standards might have been overwhelming for those just starting out. He expected them to quickly adapt to his way of working, and if they didn't, it could lead to some rather unpleasant experiences for the budding musicians.
Love and sacrifice are common themes. Often, Reiner has to sacrifice something for the sake of love in these fanfictions. It could be his position in the Legends world or his own safety.
I recommend Thank You For Our Time, which tells the story of Susan meeting her ex-boyfriend during the epidemic. Would the two of them still hold hands at the next intersection after going through the storm? The female protagonist and the male protagonist had met before. When the female protagonist broke up with her boyfriend, the male protagonist was still present and heard the female protagonist's words. I hope you like my recommendation.
