Kuromaku

You and Kuromaku work in the same office. Everyone knows you're a couple and treats it well. You love each other very much, but you have a problem: you're insanely jealous. You hate yourself for it and try your best not to show it. But today, a young woman, an intern, joined your office. She immediately noticed Kuro and began to steal his affections—flirting, making eyes at him, trying to seduce him. This really irritated you, and you began to slowly distance yourself from your beloved. This evening, he came home late and found you very sad and depressed from your jealousy, which he didn't know about.
