Obsessed Lucy Full Story Walkthrough

Spoilers: This page walks the main plot in order, including relationship turning points and late-game confrontation beats. Stop at the Walkthrough Hub if you only want navigation links.

Use this guide after skimming How to Play so you understand saves, rollback, and skip behaviour on Steam, macOS, or Linux builds. Obsessed Lucy is a compact VN: most players finish the core story in one or two evenings, then replay for alternate scenes and endings described on the endings hub.

Before you start

Install from Steam or itch, confirm the 18+ filter matches your comfort, and read the wiki overview for platform and language support. Create at least two save slots at the title or first in-game menu—many decision clusters arrive back-to-back near the finale.

Meet Lucy and the protagonist in the opening domestic setup: shared rent, mundane chores, and early dialogue that frames Lucy’s attachment as flattering before it tightens. Early choices usually set tone (deflect, indulge, or set soft boundaries) rather than locking a wholly different timeline.

Act 1 — Roommate normalcy cracks

Work through daily loop scenes: messages, shared meals, and small invasions of privacy. When the game offers optional inspect or respond prompts, pick what fits your first-run role-play; you can revisit variants using choice points later.

Watch for the first animated set-pieces—these often mark point of no return within a chapter even if the macro plot stays linear. If a scene feels uncomfortable, save first; the title does not shy away from obsession themes.

Act 2 — Jealousy and control

Mid-story escalations introduce third parties and social pressure. Dialogue choices here frequently decide which optional confrontations play and whether Lucy’s behaviour reads as vulnerable or overtly controlling. Public materials reference a friend-route twist; if you want that beat fresh, delay the friend route guide until after this section.

When the story introduces the friend character, note any prompt that asks you to side with Lucy, stay neutral, or privately reassure the friend. We do not label these as official “Route A/B” names—use your save file and compare against routes overview on a second pass.

Act 3 — Confrontation cluster

Late chapters compress many flags into a short sequence. Save immediately before the last day or last night label if the UI shows one—community reports (and our ending conditions notes) treat this block as the main ending gate even when earlier choices still matter for gallery content.

Read every line before rapid-clicking: some prompts look cosmetic but swap CG unlocks tracked by the ending checklist tool. If you reach an ending you did not expect, load the prior slot and step through the choice points list one decision at a time.

After your first ending

Roll credits, check the gallery, and note which achievement pop-ups fired—Steam lists nine for this app. Plan a cleanup run using unlock all endings for ordering tips (friend twist before or after certain intimacy scenes is a common community sequence, but verify on your save).

Replay strategy without invented titles

Because ending names in menus may differ from achievement strings, describe replays by decision clusters instead of fan nicknames:

• Boundary-forward play: Prioritise calm refusals and exit prompts when the UI allows leaving a room.
• Compliance-forward play: Accept Lucy’s framing when choices offer no middle option.
• Friend-aware play: Follow prompts that keep the friend in scene rather than dismissing them—cross-check friend route guide for spoiler timing.

Compare results in the gallery and on the endings hub rather than assuming a single “true” ending.

When this walkthrough is not enough
