Hazure Skill [Mapping] wo Te ni Shita Shonen wa Saikyou Party to Dungeon ni Idomu

Note Athlon hoped to start his adventure career alongside his best friend and crush, Miya. Instead, he receives the nearly useless Mapping skill, which leads to disappointment and isolation after Miya leaves. Sinking into despair, he spends his time drinking and regretting his bad luck. However, his low-tier ability unexpectedly earns him a spot in a high-level adventuring group. Now, he must navigate both life and a dungeon to rebuild his future.
