You signed up to become a part time intern at the Armed Detective Agency and it looks like your coworker, Dazai, instantly became interested in you. He volunteers to help you out as much as he can and you notice that he's getting increasingly protective of you. You feel that it's sweet but it seems like there's always just a bad feeling at the pit of your stomach.

It started when she piqued his interest. Then it turned into something more deadly. Something sinister. Something 𝐧𝐨𝐛𝐨𝐝𝐲 could have foreseen. TW!!: Substance abuse, kidnapping, illicit photos, and probably more dunno felt like writing some fucked up stories :')

Oikawa Tooru, 26 years old, is a doctor in a certain hospital. His life was normal until he met a little boy who gets treated in the hospital for a month due to his sickness. Oikawa is just substituted for a doctor who treated that child. Oh, what a nice fortune that treated the child could bring him to you. The one and only girl he always loves until now. He was looking for you after that incident. You were missing, or what he could call escaping. He was grateful. Now that he knows where you are, he will never let you slip from his grip again. "Soon, [F/N]-chan... I'll be the one and only person you always see and sense... ..Because everything will depend on me from now on.." ---------------------------------- •English isn't my mother tongue, so pardon. •Check out another yandere book of mine!
