May Pagsinta'y Walang Puso (Heartless Love) was a 1921 Tagalog-language novel written by renowned Filipino poet, journalist, and novelist Iñigo Ed.

A story of romance, the novel revolves around love, marriage, adultery, unfaithfulness, treachery, hatred, disowning, and forgiveness.

[2] A novel belonging to The Golden Age of the Tagalog Novel (1905-1921), the language used by Iñigo Ed Regalado was described by Roberto T. Añonuevo as a Tagalog-language that challenges the reader to study the language and the history of the Philippines, particularly in Tagalog literature.

Regalado wrote the novel when adultery was a sensitive topic in Philippine literature, thus he used language that was not obvious or vulgar, although may still be considered by Philippine society of the time as "controversial and dense in content".

Regalado tamed his language by using words and descriptions that were metaphorical, parable-like, and allegorical, particularly those that are pertaining to women.
