My Body Is Secretly in Love Without Telling Me

Lin Yi, a senior high school student, accidentally joined an "emotional love group". The couples in the group are very strange. They always like to set their names to "Brain Commander", "Big Eyed Cute", "Muscle", "Neuron", "Intestine", "Stomach"... They often quarrel over some emotional disputes and trivial matters in life, and occasionally send out some strange red envelopes. The red envelopes are marked with "memory +1", "muscle strength +2", "precision movement +3" and so on. Lin Yi always thought that this was a group of chuunibyou patients who were addicted to fantasy. Until one day, he casually pointed out a guy named "Brain Commander" in the group, and the other person sent him a red envelope with "memory +1". The moment he received the red envelope, Lin Yi's head started to heat up. ——The knowledge points that I had just recited but had forgotten suddenly became clear. "..." Lin Yi: Ah! Are you all real? Who gave you permission to fall in love in my body?
