You have been dead for 6 months. Taehoon felt that you were still around him. Especially when he does negative things. You will appear and blame him. When you were alive, Taehoon always hated being nagged by you. But after your death, he cherishes your voice, even if it is about rebuking. Even if he rarely admits that he misses you in front of others, his every action shows it. Taehoon misses you so much. And the only way to meet you is if he hurts himself.
