How Do Relationship Guidelines Shape Anime Character Arcs?

The Ivanovas and the Vitales are well-known aristocratic families who have maintained everlasting friendship through generations. My name is Anastasia Ivanova. I have been the daughter of the Ivanovas for twenty years, only to discover just now that I was switched at birth. When I was swept out of the Ivanova’s mansion like rubbish, Lorenzo, the youngest son of the Vitale family, firmly picked me up in spite of all objections. Lorenzo always acted cold and distant toward me. I didn’t know why he came to take me into his car at that time. He whispered in my ear again and again, ‌"I’ve wanted you for a long time."‌ He pinned me against the leather seat, making me cry until my voice was hoarse. At that moment, I finally understood his coldness over the years was not indifference but restraint. Soon after, Lorenzo overrode all objections to marry me. His parents were vehemently against me, but Lorenzo directly stripped them of power and became the youngest godfather. Scarlett Montgomery tried to stop us from getting married, but Lorenzo canceled all her credit cards and threatened to send her away. I thought we would have a happy life. Three days before our wedding ceremony, he planned to send me abroad, claiming enemies might retaliate. But, I accidentally overheard him talking to Scarlett in the hallway at night. "Thank goodness. You tricked her into leaving until after I give birth. You’re so good to me!"‌ He kissed her cheek, ‌"I don’t want Anastasia know our affair. You must keep it secret."‌ Their dialogue made me devastated. But I didn’t confront him immediately. Instead, I quietly completed my immigration paperwork as a way to make a clean break with him.

Hiraya is an intelligent and independent girl who is considerate of others, but she has an inferiority complex. She does not accept her appearance, she feels like it is disconnected from her body. Hiraya works in a company owned by Tanashiri's dad, and Tanashiri is a rude and arrogant guy with an obsessive-compulsive disorder. Contrary to popular belief, he just hides behind that mask-there is more to it than people see on the surface. He also does not feel connected to his existence. Little did they know that the past explains why they behave that way.

My roommate was obsessed with those cheesy “milk-scented girl” romance stories. She wanted to become the kind of heroine from those books. Tiny, soft, and delicate, the type who was supposedly so sweet that even her farts smelled like milk. So she went completely overboard. She lived on dairy. Drank milk nonstop. Even took milk baths. She tried everything, all because she was convinced she’d eventually run into her destined male lead. I believed in letting people make their own choices. What I didn’t expect was for her to go after my boyfriend, the guy I’d basically grown up with. One day, she sent him a carefully posed thirst trap. He replied with one word. “Get lost.” Then she proudly showed me the screenshot, like she’d won something. “Only girls like me, soft and sweet and irresistible, deserve a powerful man’s obsessive love.” “Don’t be fooled by how cold he is now. He’ll be crazy about me soon enough. He’ll want me all to himself.” I was just about to tear into her when a row of floating comments suddenly appeared in front of my eyes. “Fresh one, guys. This host is bold. Coming in with a thirst trap right away? Nice.” “Wait, what? Isn’t this just harassment? The male lead already has a girlfriend.” “Bro, I think you’re in the wrong livestream.”

In real life, I had been pushed to the brink by an online romance scam. Just when everything fell apart, I awakened something called the Devotion System, and before I could make sense of it, I found myself thrown into a horror game. Among all the players, I was the weakest, barely able to take care of myself. If I wanted to survive, I had only one option—find someone stronger and cling to them, no matter what it took. However, things did not go the way I expected. Every player avoided me like the plague. Not a single one was willing to team up. With nowhere left to turn, I made a desperate decision. I chose a ghost. I treated her as my bound partner and devoted myself completely to her, clinging to her as if my life depended on it. However, as I spent more time with her, I began to realize she was not just something terrifying. She was someone who had been hurt, someone deeply broken. Hence, I stopped pretending. I began to help her sincerely. In the end, we overcame everything together and cleared the game. However, when I returned to the real world, I discovered something I never could have expected. She had followed me back. From that moment on, all I could do was wait for the system to pull me into the next stage.
