This only pure fan fiction I don't own anime's and manga's that I use on my fan fiction.
Other characters of my mine are made by me.
And there's no harem in this novel but I'm giving Shiro some potential partners and some lovely cliche romance but I only give one partner for Shiro until the end of my novel but there's also some cliche childhood romance and some self proclaimed fiance so that there's also comedy into these novel

There might wrong grammar in my novel but I'm working on it and if there's something wrong or you want me to add something please tell me. Because this is my first fan fiction. And please don't hate me for stealing some dishes that aren't mine because I'm not a great cook in my life. Please I'm so sorry in advance. And if the chapter is short I'm working in it in the future.
