Most of Hee-do and Yi-jin's world is one walkable Jeonju neighborhood — the tunnel, the house and the comic shop sit minutes apart around the Hanok Village.

1Hanbyeok Tunnel

The 60m railway tunnel where Hee-do and Yi-jin confess — and where they break up in the finale.

Address
Beside Hanbyeokdang Pavilion, Gyo-dong, Wansan-gu, Jeonju, Jeollabuk-do
Getting there
KTX from Yongsan to Jeonju (about 1h50m), then a 15-minute bus or taxi to the Hanok Village; the tunnel is a short walk past Hanbyeokdang Pavilion.

💡 Free to walk through, prettiest with summer greenery — and it chains straight into a Jeonju Hanok Village afternoon.

2Na Hee-do's house

The white-gate house under the streetlamp where Hee-do lives and first meets Yi-jin at night.

Address
50-37 Gyo-dong, Wansan-gu, Jeonju, Jeollabuk-do
Getting there
A 10–15 minute walk from the Hanok Village center.

💡 The former guesthouse here has closed — it's an exterior photo spot in a residential alley, so keep it quiet.

3Comic rental shop, Seohak-dong Art Village

The book-rental shop where Hee-do reads Full House daily, setting for several of the pair's scenes.

Address
Seohak-ro, Wansan-gu, Jeonju (across Namcheongyo Bridge from the Hanok Village)
Getting there
10 minutes on foot from the Hanok Village across the stream.

💡 The surrounding art village is full of cafés and craft shops — a natural half-day loop with the tunnel and house.

4Paldalmun Gate, Suwon Hwaseong

The hillside bus stop beside the fortress wall where Yi-jin ties Hee-do's shoelace — revisited in the finale.

Address
Paldalmun area, Jeongjo-ro, Paldal-gu, Suwon, Gyeonggi
Getting there
Line 1 or Suin-Bundang Line to Suwon Station, then a 10-minute bus to Paldalmun; stairs by the tourist booth lead up to the wall.

💡 The bus stop was a prop — no real bus stops there. You're on the UNESCO fortress wall, so keep walking it.

5Geumjin Beach

The quiet east-coast beach of the episode-10 summer trip.

Address
Geumjin-ri, Okgye-myeon, Gangneung-si, Gangwon
Getting there
KTX to Gangneung (about 2 hours), then a 30-minute local bus or taxi south toward Okgye.

💡 Far emptier than Gyeongpo Beach, and the Heonhwa-ro coastal road next to it is one of Korea's most scenic drives.

The Jeonju pilgrimage

Three of the five locations cluster around Jeonju Hanok Village, Korea’s best-known traditional district — which means the drama trip doubles as the classic Jeonju day: hanok lanes, bibimbap (this is its birthplace), and the tunnel-house-comic-shop loop on foot. The school scenes used a working school in Nonsan (not visitable), and Yi-jin’s rooftop room is a private home — street view only.

Combining trips

The Suwon fortress stop shares a neighborhood with Lovely Runner and Extraordinary Attorney Woo locations, and Geumjin Beach extends the standard Gangneung KTX day (Goblin’s breakwater, the BTS bus stop) 30 minutes further south.
