The main characters are reincarnations of the people who committed suicide, it’s a fantasy story.
And Thai BL puts all the disclaimers they can on every BL series that the subject matter is not meant for younger audiences. Just as the tv or movies get rated in other countries.
This series does not romanticize or validate suicide in any way.
In fact the Buddhist belief in karma is heavily emphasized in this series, the actions of the two main characters (good or bad) in ending their lives as they do, in some ways negatively impacts their reborn selves.
I missed the conversation, but that could be a Japanese BL.
Their country is more well known to have more diverse ages and subjects for their storylines.
No fortune cooke "fortunes". Examples:
Good things come to those who wait.
Your hard work will soon pay off.
A pleasant surprise is waiting for you.
You will discover something valuable.
Your kindness will be rewarded.
Adventure awaits you.
Happiness is closer than you think.
A new opportunity will soon appear.
Your future is looking bright.
Now add the words "in bed" to each of those.
