After drinking a large cup of ice cream milk tea, Su Bei felt refreshed for a while, but suddenly, her stomach began to cramp. At first, Su Bei thought it was a normal stomachache, but later realizing that she was actually getting her first period!
                          
In that parallel world, Su Bei lived until she was eighteen years old and had some experience in this area. But her physical condition at that time wasn't very good. Her first period came when she was almost eighteen. So, after returning to this body, Su Bei never considered this problem before.
                          
Unexpectedly, her period came today.
                          
Su Bei curled on the bed in pain. She inwardly thought: is it because her living and eating condition is now so good, so her 'relative' come earlier?

Meanwhile, Su Xiaobao was doing an olympic-level problem set in his room when Su Bei suddenly called his phone. The boy was stunned: Su Bei is in the next room; why is she calling him on the phone?
                          
Su Xiaobao answered the call. Su Bei's voice immediately came from the receiver: "Xiaobao..."
                          
The girl's voice didn't seem right. Su Xiaobao was surprised and asked: "What's happen?"
                          
Su Bei: "Come here quickly."
                          
The next second, Su Bei yelled across the wall: "Su Xiaobao!"
                          
"I'm coming." He still has to wear his slippers first.
                          
Su Xiaobao went into Su Bei's room, only to find her curling on the corner of the bed, stiff and motionless. Su Bei's complexion was terrible, and her face was distorted in pain. Seeing her condition, Su Xiaobao was panicked.
                          
"What's wrong with you? Are you sick? Does your stomach ache?"
                          
Su Bei nodded, then shook her head.
                          
Su Xiaobao: "I'll call a doctor."
                          
"Don't!" Su Bei stopped Su Xiaobao: "I'm not sick."
                          
Su Xiaobao frowned deeply: "You obviously look sick."
                          
"No, this is normal. It's just..." Su Bei was tangled.
                          
"I don't understand."
                          
Su Bei suddenly took Su Xiaobao's hand and looked at the boy with a pitiful face: "Su Xiaobao, can you help me buy something?"
                          
Su Bei then used a lot of explanation to make Su Xiaobao understand what she needed.
                          
"Okay, I'll go. Wait here." There was no way, Su Bei was still in pain, he couldn't let her go by herself.
                          
Su Bei: "Wait, do you know what kind of product to buy?"
                          
Su Xiaobao: "Didn't you tell me just now?"
                          
"Wait a moment, I will draw a picture." If she didn't give him exact instructions, Su Xiaobao might be driven crazy by the frightening number of different products on the store shelves.
                          
Su Bei took out a pen and paper, then drew the type of sanitary napkin she needed.
                          
Su Xiaobao: "Epsilon x 3?"
                          
Su Bei: "What epsilon?"
                          
"Didn't you draw it yourself? This." Su Xiaobao pointed at the reversed '3' on the drawing. His face was completely serious.
                          
"That's not epsilon! That's a pair of small wings!"
                          
"What kind of wing is this?" Su Xiaobao complained.
                          
"Well, don't say anymore." Su Bei clutched her stomach and said: "Go quickly. If you can't find it, just give the picture to a female shop assistant."
