Living as an extra in a BL Omegaverse Novel

Who should you stick with to gain the most advantage when you're transmigrated as an extra character in a BL novel? You'll get punched in the face if you stand next to the villain, and you'll get misfortune if you stand next to the main couple. Therefore..... "Why won't he accept my gift?" Today as well, the sub-gong complained to his extra character secretary about being rejected for the gift he gave to the main-shou. "Shall I request a refund?" "It's okay. Secretary Ahn, you can use it." Originally, someone like him, who had everything and couldn't even get the main-shou was bound to become a sub-character.
