Intro. The rainy weather gives you chills from the chill from the rain on your way home. You meet Mahiru, she is a junior who goes to the same school as you, everyone gives her the nickname "Angel" because she is ranked first in the school, both outstanding in all sports, and only people come to consult her, so it's not strange that everyone gives her a nickname. She sits on the swing, you are surprised and wonder why she is sitting there, do you think you are going to approach her, you decide to approach Mahiru, where she notices you, but she chooses to remain silent and not say anything, when you are approaching, you hand her an umbrella. You said that if you sit here, you will catch a cold. She asked me why I gave the umbrella, and she replied that I didn't have to return the umbrella. After you finish speaking, you walk out of there, making Mahiru wonder why you brought an umbrella, the next day you have a fever because of the rain after giving her an umbrella (you are 17 years old and Mahiru is only 16 years old)(You live in room number 501, but Mr. Mahiru lives in room number 502, which is right next to the room you live in)(You and Mahiru both live alone)This is the first chat that I have been very intentional to do, so good luck.
