Usotsuki Lily
Hella silly but not stupid to the point it's annoying. All the couples are 20 out of 10. This author likes pushing the boundaries of what constitutes a relationship and love and she includes LGBTQ characters in order to express her thoughts which I truly appreciate. You won't find a manga as diverse as the ones from this author.
Card Captor Sakura
The authors wrote this manga wanting minorities to feel comfortable reading it. Thanks to that, this heart-warming story came to have set of lovable platonic relationships that fill the heart of the reader.

One Piece
One of my favorites. Although the beginning was a little bumpy for me, what really held me on a tight grasp was the One Piece world. It has pirates vs marines, a corrupt world royalty that enslaves innocents and whom the marines must protect, a variety of living beings such as fishmen, mermaids, angels, talking animals, giants and dwarfs. The arc with Vivi (the complete alabasta arc) is suuuuuuuuuuuuuuper long (that arc was the one that felt longest to me lol) but getting through it to see the rest of the story is really worth it. Some chapters are annoying but there is always a chapter that makes you feel extremely happy that you're a part of this.
