Tonari no Yasawa

Histoire

Ever since they were kids, Kaoru and his childhood friend Toyoko have had one rule: the loser in judo buys the winner a meal. But now that they’re in high school, Kaoru just can’t keep up—Toyoko only gets stronger every year, and he’s stuck paying the bill. After yet another crushing win, Toyoko teases him with a snide remark… and Kaoru finally snaps. He stakes everything on a final match: “If I lose this time, I’ll buy you meals for the rest of my life!” A judo bout to decide their future — rivalry, pride, and maybe something more are all on the line!
