Fanfictions should focus on positive, family - friendly and creative aspects rather than such improper content. So I won't discuss this particular one.
Look for fanfic communities dedicated to MHA. Sometimes, they have specific sections or tags for more unique or educational - themed fanfics. You could also try reaching out to other MHA fans and ask if they know of any such fanfics. But always be cautious about the content you might encounter.
There might be some fan - fictions that touch on themes related to sex education in the context of the MHA world in an appropriate way. For example, it could be about how the characters learn about relationships, respect, and boundaries which are aspects of sex ed. However, it's important to note that such fanfics should be in line with the general ethical and moral standards of the fandom.
The relationship could develop slowly. Deku would likely admire Tsuyu from afar at the beginning. Then, they could be involved in group activities where they start to work together more closely. Deku would notice Tsuyu's kindness towards others and her determination. Tsuyu, in turn, would see Deku's growth and his unwavering spirit. As they get to know each other better, their relationship would progress from acquaintance to friendship and then to something more romantic.
In tsuyu lemon fanfiction, one characteristic could be the exploration of Tsuyu's personality in a different light compared to the original source. It might also include scenarios that are not part of the official story, like her being in a romantic relationship with a particular character. And due to the 'lemon' aspect, there could be some degree of physical closeness and emotional vulnerability depicted in a more explicit way.
Tsuyu Lemon fanfic often emphasizes their contrasting personalities. Tsuyu is usually calm and collected, while Lemon might be more energetic. So, the fanfic may play on these differences for comedic or dramatic effect.
Another fanfiction could be set in an alternate universe where Naruto and Tsuyu are students at the same school. They could be in different classes but end up working together on a school project. Tsuyu's calm and collected nature would contrast with Naruto's more boisterous personality, leading to some interesting interactions and character development.
They can start with simple acts of kindness towards each other. For example, Deku could offer to help Tsuyu with her studies, especially in hero theory, which he's good at. Tsuyu, in turn, could share her insights on how to better use one's quirk in real - life situations. This mutual exchange of help can gradually build their connection.
