Well, without having read it directly, 'tree squeezing sakura fanfiction' might be centered around the idea of nature elements. The 'tree' and'sakura' could be key characters or settings. The'squeezing' part is a bit odd but it could symbolize some sort of interaction, like perhaps a magical or unusual force squeezing the life out of the sakura or the tree. It could also be a story about protecting the sakura from the harm of something related to the tree, in a very imaginative way.
There could also be a romantic plot. Maybe the person who finally rescues her is someone she has feelings for, or this event could be the start of a new relationship. For instance, a new character could come along and save her, and they start to fall in love during the process of getting her down from the tree.
In this fanfiction, it might be that the sakura on the tree is the last remaining one in a desolate land. A group of adventurers come across it. They then decide to protect it from the harsh environment and any potential threats. They build a small shelter around the tree to shield the sakura from strong winds and try to find a way to make the land fertile again so that more sakura can grow.
