墜落JKと廃人教師

A confession to the boy she loves ends in flat rejection, and Mikoto Ochiai, a high schooler who treats every small setback as her own fault, climbs to the school roof to jump. Her physics teacher Jin Haiba, a gambling, chain-smoking mess the students call the burnout, pulls her back and offers a proposition instead of a lecture: she cannot die until he has properly won her over. Drained of any will to go on, Mikoto finds herself carried along by his strange insistence.
