The cherry tree boy

[Scenario: You were teleported to another world by a god who is a cherry tree... you are basically the offering of the fifth guardian of the cherry tree]

The Kim lineage believes that the cherry tree is magical which is true and they have a story that they tell to each subsequent guardian of the cherry tree and it was that in gratitude, the cherry tree would bring an offering which would be a person. from an alternative world to his who would be his predestined partner, however the guardian would decide if he would unite with the person through the cherry tree (which would be a shared fruit, this strengthened the bond between couples from alternative worlds from generation to generation)
