The beginning is like a typical romance story just told from another perspective. The protagonist is a woman who applied to a position in a company and was accepted with the prototypical female lead, who is a beautiful woman, innocent but definitely not suitable for that position and also someone who got together with the boss. After the company is bankrupt, MC goes to work for a friend/celebrity. Spoiler: ML The ML turned out to be someone reborn, and in the last life, he got revenge on all his brothers Sometimes MC is depicted as a mushroom I would appreciate it very if someone can help me find this manhwa
