Chiaki-kun Mimamori Club

High school student Koma Taisuke experiences an unexpected interruption during his ordinary morning commute. While walking to school, he is approached by a complete stranger who greets him with the cryptic words, "We finally meet again." Caught off guard by the sudden encounter, Taisuke is left bewildered, unable to place the mysterious young man or understand why he seems so familiar. The confusion only deepens later that day when a new transfer student is introduced to Taisuke's class. To his astonishment, the boy standing at the front of the room is none other than Chiaki Kei, the very same stranger who stopped him on the street that morning. As if the coincidence were not startling enough, Chiaki makes a bold and perplexing declaration in front of everyone: he claims to be Taisuke's childhood friend. With no memory of such a bond, Taisuke finds himself thrust into an unusual situation, forced to navigate the persistent presence of a classmate whose shared past remains entirely unclear.
