Then again, he would have found out sooner or later due to the small things that made him stand out and just be different.

However no one knew anything about a small child which lost his mother and was adopted by a kind pair of humans... who inevitably think their own lives matter more than the childs and make him do all kind of stuff.... Oh if things could only go differently.... oh if only Iruma would finally find the meaning behind that paper he still had from his mother sooner.... oh if only! A/N: This is a Iruma fanstory hope you enjoy! Please also feel free to correct my bad writing. Rights on the pictures go to the artist. I do not own iruma, rights to the owner.

    Trước khi đọc tiếp thì mình nghiêm túc cảnh báo là chuyện này có yếu tố "Age gap" và" Thầy trò ". chắc chắn mình sẽ không đi quá giới hạn mà đụng chạm vấn đề 16+ khi nhân vật chưa đủ tuổi và ở trên ghế nhà trường nên mọi người yên tâm, chỉ là một góc " ảo tưởng" của mình về OTP thôi :)))). Mọi thứ mình viết dựa trên mạch truyện gốc một phần và sẽ có sự thay đổi vì không phải theo truyện gốc, và mục đích sau cùng là để thỏa mãn con đói hàng như mình thôi :)))) ---------------------------------------- Ánh mắt, đôi môi, một hơi thở Trong vắt, bồi hồi, dạ da diết Thiết tha sâu đọng bóng hình em Cả một khoảng trời thương viết tiếp." ---- "Thanh xuân của tôi thiếu sót nhất là khi thiếu em, mùa xuân nhỏ tràn đầy sức sống của tôi.."

    This is the story of Lilith Rahu, a demoness attending Babyl's demon school. She has a violent nature and a bad mouth, even for a demon she is considered crazy. But she quickly finds herself thrown into a friend group of a human and two demons after a rather strange first day at school. She finds herself building bonds quicker than she can think about it and soon her demonic nature turns into something much more pleasant. But the bonds she builds with a certain fire magic user slowly takes a turn towards something much deeper than just friendship if it weren't for the secret she has to keep from everyone she loves. Warning this contains: *Cursing* (A LOT), violent behavior, romance, and mentions of blood (?) Also Mairimashita! Iruma-kun belongs to Osamu Nishi, I only own Lilith. I simply write as a hobby... Also I go with the Manga so *SPOILERS*!!!!! Aight! Time to sleep! (I'll update Once every two weeks)
