One of the best Shonen romances is The Dangers In My Heart. The main character Kyoutarou acts like an edgelord, but in reality he’s socially insecure and uses that edginess to hide his true feelings. When he gets closer to his crush Anna Yamada, he gains confidence and experiences what a romantic connection feels like. That’s why this anime appeals to teenage boys. They relate to what Kyoutarou is going through. The anime also showcases the difference between what pure romance and physical attraction looks like. They’re allowed to be vulnerable with each other and support each other in tough times. Boys eat that stuff up just as much as girls.
