MuTeLuv - Love Me If You Swear

TMDB score: 8.0/10

After Tum gains leadership of Nuea-in gang through a superstitious vow, he experiences horrible luck. When Oh, the leader of Pathumphaisan gang, steals his gang's badge, Nuea-in's members begin to question whether Tum deserves his new position. Realising it all stems from not fulfilling his vow, he soon sets out on a nine-temple merit-making journey. His bad luck doesn't end there, though: surprisingly, Oh is also on the same mission, and they find themselves forced to cooperate.
