@Woofwoof Possible matches (best-first)
1. “Sign” (manhwa) — has a coffee-shop setting and a younger guy who works there; readers sometimes mix up details (it’s explicit and involves a shop romance). Might match the coffee shop + reunion beat.
2. “Love Is an Illusion!” — popular BL/manhwa about school/young adult guys with lots of breakups/returning-home tropes; readers often recall emotional break + reunion scenes even if small details differ. (Doesn’t obviously have the fridge-note scene, but it’s a commonly confused title when people remember a top/uke school romance.)
