The afternoon sun shines through the gaps in the curtains and onto the protagonist's face.He opened his eyes drowsily, but the surrounding environment made him wake up instantly - everything changed, and he came to a BL world.The protagonist has mixed feelings in his heart, but he firmly tells himself that he cannot follow the crowd and maintain his position.

After returning home, instead of indulging in the fantasy of this new world, the protagonist quickly takes action.He bought a bunch of BL novels and immersed himself in studying the basic structure of the world, trying to find a solution.He is determined to fight to the end, learn how to be a real passerby, and try his best to avoid any love stories.

However, life is always full of surprises.Just as the protagonist was sitting on the sofa, thinking hard about how to become a qualified background passerby, his younger brother suddenly burst in with an excited blush on his face and told him that he had been confessed to by a boy.When the protagonist heard the news, his heart collapsed and he quickly warned his brother that this was just adolescent ignorance and he must not be fooled.

Watching his mother's longing for love in the TV series, the protagonist couldn't help but fall into deep thought.He began to think about the factors that produce love and tried to find ways to avoid it.He told himself that he must always be vigilant and not let himself fall into the whirlpool of this BL world.

On the way to school, the protagonist has learned the secret of being a good passerby.He carefully avoids factors that may trigger love, such as not bumping shoulders with gangsters on the road to avoid inexplicable feelings.During lunch time at school, he also tried to avoid situations that might lead to romantic encounters, such as a guy meeting a lively and cute girl by chance, and then successfully getting the two together through his mastery of delicious food.The protagonist watched all this from the side, feeling both understanding and contented.

When I was taking a shower at night, my brother suddenly broke into the bathroom and commented on the protagonist's figure.The protagonist was shocked and began to wonder if his brother had some unusual ideas.He quickly stopped his brother's conversation and asked him to go out quickly.

Going to school the next day, the protagonist breathed a sigh of relief, finally ending the day of defense.However, my friend extended an invitation to have dinner together.The protagonist originally wanted to refuse, but in order not to become a lone ranger-like protagonist, he hesitated and decided to go together.Although the friend was surprised, he agreed and invited a handsome lone ranger guy to attend the dinner together.

During the dinner party, the protagonist carefully maintained the role of a passerby and tried not to let himself become the focus.However, the handsome lone ranger seemed to be interested in the protagonist, and he looked at him with concern from time to time.The protagonist felt nervous and quickly lowered his head, pretending to be concentrating on eating.

After the dinner, the protagonist breathed a sigh of relief and finally spent another day without a love story.He understands that in this BL world, he must always be vigilant and not let himself fall into any possible love whirlpool.He will continue to work hard and be a real passerby until he finds a way back to his original world.
