Don't Approach Characters the Wrong Way

When she woke up and found herself in a different world, Saya Asakawa was confused. However, the system in her brain was clamoring for her to use fan fiction routines to defeat the characters. ① System: You have to patiently take care of him, help Hei Nijing who misses work to write reports, do work, and make coffee. You have to fish him out of the river every day, use love to dispel his loneliness, and inspire and save him! Saya: (with a sad face) Mr. Dazai, please don't die like this... (Heart: Give me the work before you die) Black Mud Essence:...... ② System: You have to attend the dinner party with the hat rack cadre as a lover. Trick him, surprise him, attack him when he's drunk! Although he is a mafia, he is still an innocent little brother~ Saya: (dead eyes) Obviously I can attend as a subordinate... ③ System: Go and meet a famous detective! You have to feed him snacks, take care of him and pamper him, and the detective cat will get close to you and fall in love with you! Saya: ... Are you sure he loves me and not the snacks I feed him? … Saya: I've had enough, I want to die and go home :) Early Warning 1. The heroine is not a lover, she just wants to go home 2. The heroine who thought she was good at pretending was actually seen through 3. There is a single arrow, a Shura field, and the cp ending is determined (it may also be open-ended) Purpose: Use your sincerity to win love
