 The Thai title means, literally, "Love Story, a Little, a Lot" with  a play of words on "Noi" and "Nid" which means "few" and "small"  respectively. The two words are also the names of the sisters in the  movie so the title can also means "Love Story of Noi and Nid, a Lot"  (mahasan = infinitely a lot, a great amount). Another interpretation  can be "A small/little Love Story that is a lot".
