What to Watch After Signal: Three K-Dramas That Hit the Same Note
If Signal left you with dread, duty, and hope caught in your throat, these three dramas answer that ache.
Signal works because its time-slip hook is never a gimmick. Park Hae-young (Lee Je-hoon) reaches a detective in 2000 through a vintage walkie-talkie, and every cold case carries grief that someone failed to answer in time. Lee Jae-han (Cho Jin-woong) keeps moving because duty is the only promise he can still keep. Cha Soo-hyun (Kim Hye-soo) gives the present its weight: the past is not finished just because everyone learned to live around it.
1. My Mister
Similar platonic-deep grief register as Signal. 2018, tvN.
Pick My Mister if the bond between Hae-young, Jae-han, and Soo-hyun was the part you could not shake.
The genre changes completely. My Mister is not a procedural, and nobody is working cold cases across time. Park Hae-young’s 2018 tvN drama follows a 45-year-old engineer and a 21-year-old temp at Saman Engineering as they become each other’s only safe place. That sounds quieter than Signal, but the match is real: grief, isolation, tenderness, healing, and a platonic-deep relationship engine.
What carries over is the ache of being heard. Signal turns that need into a literal transmission. Someone in another year answers. Someone believes the case still matters. My Mister brings that same hunger into ordinary life, where the rescue is not a solved file but one human being refusing to look away from another.
Choose this when you want the sadness to slow down. Signal keeps pushing because lives are at stake. My Mister sits with people after the damage and asks what kind of care can still reach them.
2. Vincenzo
Similar dread-and-duty pressure as Signal. 2021, tvN / Netflix.
Choose Vincenzo if you finished Signal wanting corrupt power to feel cornered.
Park Jae-bum’s 2021 tvN / Netflix drama follows an Italian-Korean mafia consigliere who returns to Seoul for hidden gold and ends up taking down the corrupt Babel Group. The tone is louder and more vicious than Signal, with plot-dense pacing and a cathartic ending instead of an ambiguous one. Still, the taste match is clear: dread, duty, revenge, class friction, and the pleasure of watching people with protection discover that protection can fail.
That matters after Signal because Hae-young and Jae-han are not only chasing clues. They are fighting the rot that lets old harm harden into public record. Vincenzo takes that anger out of the evidence room and into a bigger, nastier fight. It is less haunted by unsolved grief and more interested in payback, but the moral appetite is familiar.
Pick this when the ambiguous ending leaves you needing release. Signal keeps hope tense. Vincenzo lets consequences arrive with teeth.
3. The Glory
Similar dread and long-memory revenge pull as Signal. 2022, Netflix.
Pick The Glory if the cases in Signal left you thinking about what happens when nobody answers in time.
Kim Eun-sook’s 2022 Netflix drama follows a bullying survivor who spends 17 years engineering revenge against the five tormentors who walked away free. It is not a police procedural, and its relationship engine is revenge-target rather than platonic-deep. But the emotional overlap is strong: dread, betrayal, isolation, revenge, slow-burn pacing, and a cathartic ending.
Signal hurts because the dead and the missing still feel present. A case may be cold, but the loss is not. The Glory follows that same refusal to let time clean the crime. It gives you a survivor who does not accept the world’s request to move on politely.
This is the darkest follow-up of the three. It does not give you Jae-han’s stubborn warmth or Hae-young’s desperate hope. It gives you patience, receipts, and the terrifying calm of someone who remembers everything.
Choose it when you want justice without comfort.
What you actually want next
If you wanted the human signal beneath the cases, pick My Mister. If you wanted duty to turn into payback against protected people, pick Vincenzo. If you wanted the wound of a crime that time never healed, pick The Glory. That is the real choice after Signal: quiet repair, loud consequences, or long revenge.
