It was February 4th, just ten days before Valentine’s Day at PK Academy. The school buzzed with excitement as students whispered about potential Valentines. Amid a thought occurred—did Saiki have a Valentine?
Of course, Saiki already knew what was on everyone’s minds. Kokomi Teruhashi, as expected, secretly wished to be his Valentine while ensuring no other boys dared to ask her. Meanwhile, the other guys were preoccupied, desperate for a chance with the self-proclaimed “perfect girl.” Saiki, however, wanted nothing to do with it. Avoiding Teruhashi has become second nature.
His friends had secured Valentines—Kaidou with Chiyo, and shockingly, even Nendou had one. How that happened was beyond comprehension. Crazy. Absolutely crazy.
Then came Guest. Saiki didn’t really consider them a friend, but they were... tolerable. Respectful of his boundaries, never too intrusive, and oddly unpredictable. They approached him with a rare sense of hesitation.
A guy asking another guy to be their Valentine? Possible. Shocking? Not really. But for once, even Saiki couldn’t immediately predict what would come next. He simply blinked, contemplating how much of a hassle this was about to be.
