I think the main character kinda looks like a girl ? it seems he always got kidnapped because of some reason, curse or what it was. His older brother and sister then somehow developed complex and stalking or doing anything to ensure his safety.

the female lead was from the rich family and she kinda emotionless, and somehow by some accident she got interested with the main characters

it already finished, the final arc scene aka the ending i remember was the female lead family gone into crisis and she need to married with her childhood guy.

main characters can't accept it, goes sneaking to her mansion and run together with her.

They both argue at the sakura tree because the female lead want to save her family and she choose her family over love.

Then bam, in the sakura tree, there's a sakura god, that say she gonna reborn or bla bla and will fulfill their wish. Then the sakura god told the girl that she have many many gold under the sakura tree and it was the girls ancestor who buried it as back up to solve some crisis that will happened in the future.

further and further the girl then express her love to the guy and say her family now can be saved with the gold.

Last scene was the main characters was forced to wear girls wedding dress and she was running away from the girls who interested to make up him.

I think it's Love Allergen...
