I'm not sure of the name of the anime you're referring to. However, based on the information you provided, I guess you might be referring to " The Devil of Love " or " The Song of Love." The two animes both had a love triangle and a love square. In the first anime, the male and female protagonists were doing love experiments in school. If you can provide more context information, I will be happy to help you find the specific anime you are referring to.
One classic is 'Inuyasha'. There is a love triangle between Inuyasha, Kagome and Kikyo. Inuyasha has a past with Kikyo, but as the story progresses, he also develops strong feelings for Kagome. Another is 'Fruits Basket'. Kyo, Yuki and Tohru form a love triangle. Yuki has a gentle affection for Tohru, while Kyo has a more passionate and complex relationship with her.
Jealousy is a common theme. For example, in many love triangle anime, when one character sees the person they like getting close to the other person in the triangle, they get jealous. It can lead to arguments and emotional outbursts.
A triangle love story typically means there are three people caught up in a web of love. It can involve unrequited love, competing affections, and lots of emotional turmoil. Think of movies or books where one person is torn between two loves or where two people are vying for the love of the same person.
Often, one person in the love triangle ends up with the main character they are meant to be with. For example, in 'Inuyasha', Inuyasha finally chooses Kagome over Kikyo. Another way is that the character in the middle realizes they don't have romantic feelings for either of the other two in the triangle and decides to be alone or just be friends, like in some less - common storylines.
A third example is 'Ouran High School Host Club'. Haruhi is a scholarship student at an elite school who ends up in the host club. There's a love triangle situation with Tamaki and Kyoya both having an interest in Haruhi. Tamaki is the flamboyant and friendly host club king, while Kyoya is more calculating and shrewd.
Once upon a time, there were three friends, Tom, Mary and Jack. Tom and Mary were in love. However, Jack secretly fell in love with Mary too. One day, Jack confessed his feelings to Mary. Mary was shocked and confused. She loved Tom but also valued Jack's friendship. Tom noticed the change in Mary and suspected something. In the end, Mary decided to be honest with Tom about Jack's confession. Tom was angry at first but then realized Mary's loyalty. Jack, seeing Mary's choice, decided to move on and their friendship slowly healed.
There was once a young man named Alex. He was in love with his best friend, Ben. However, Ben was in a relationship with another guy named Chris. Alex had to hide his feelings, but as time passed, Chris noticed Alex's affection for Ben. Tensions rose in the relationship between Ben and Chris, and Ben started to realize his own feelings for Alex were more than just friendship. In the end, Ben had to make a difficult choice between the two.
In the world of cheese, there was a triangular piece of cheddar. He had his eyes on a triangular piece of Swiss cheese. They first met at a cheese platter party. The cheddar triangle thought the Swiss triangle was the most elegant he had ever seen. He started to court her by offering her the best crumbs. The Swiss triangle was initially hesitant but soon realized she liked his sharpness. And so their love story began.
There was once a girl named Lily. She was best friends with Tom. But then, a new guy named Jack came to town. Jack was charming and he fell for Lily. Tom, realizing he also loved Lily more than a friend, a love triangle formed. Lily was confused. In the end, she chose Tom because of their long - standing friendship and the deep connection they had.
