HP Redemption: That Touch of Light Blue

Mary Sue's warning, there is a system, everyone is attracted to everyone, both men and women are included, official matching is split, parent generation + child generation, with nose soup play, and the final ending has no cp, which means that the heroine will only be alone in the end, but she will be together in the branch line and separate the if line. A puddle of spring water overturned, she was like the clear moonlight at night falling in everyone's heart, her existence was as dazzling as a god. ——Zi Draco × Wen Er (arrogant young master × rival girl) "I hate you, Wen Er." "I hate you too, Malfoy." I hate that you will never see me in your eyes. —— Hermione × Wen Er (nagging academic master × bad academic friend) "We are friends." "Of course, you are my best friend" But, I don't want to be just friends with you. —— Ron × Wen Er (Glutty Puppy × Gentle Angel) "Wen'er, the chicken legs are yours, you're too thin." "Thank you Ron, you are the best!" Actually, I also want to belong to you. —— Harry x Wenle (savior x his savior) "Do you like me?" "I like it." But you only like me as a friend. —— Theodore × Wen Er (Paranoid Boy × Mysterious Girl) "I will find it." "What did you find?" I will find proof that you love me even though you don't love me.  …I won't write anything else now, as I can't fit it in the introduction. … Finally, may the magical world be with you.
