Init sa Magdamag (International title: When Love Burns /) is a 2021 Philippine television drama romance series broadcast by Kapamilya Channel. Directed by Raymund B. Ocampo and Ian D. Loreños, it stars Gerald Anderson, Yam Concepcion and JM de Guzman. It aired on the network's Primetime Bida line up and worldwide on TFC from April 19 to September 10, 2021, replacing Walang Hanggang Paalam and was replaced by Marry Me, Marry You.
The story revolves around Tupe, Rita, and Peterson — and their love triangle marred with political drama and clashing dreams.
An aspiring doctor, Tupe gets falsely accused as being involved in the corrupt activities of his government official associated father, wrecking his relationship with Rita. Years after Tupe's apparent disappearance, Rita finds a new love in Peterson, who credits her for becoming a changed man as he pursues political office.
Rita and Peterson's relationship began to deteriorate after Peterson was rendered impotent due to a car accident. Believing that having a child will revive their failing marriage, Rita and Peterson decided to hire a sperm donor — in the form of Tupe, who is now a resident barrio doctor. Unbeknownst to Peterson, Tupe is Rita's greatest love. Complications will soon arise when Peterson unravels that truth behind Rita and Tupe's past, igniting his rage.
Maja Salvador was originally cast to play the titular role with the working title Ligaya back in 2018 but she turned down the role because of its infidelity-themed concept similar with her previous teleserye, The Legal Wife, and also out of consideration for her current boyfriend.[2] [3] Yam Concepcion took over the role.
The series began airing reruns on Kapamilya Channel's Kapamilya Gold afternoon block and A2Z's Zuper Hapon on March 28 to August 26, 2022, replacing the rerun of Love Thy Woman and was replaced by the rerun of Bagani. It also aired on Jeepney TV as simulcast from Kapamilya Channel, A2Z, and TV5 from April 19 to September 10, 2021; and aired as reruns from May 14 to November 12, 2023.
