All Scenes

Every scene in the game, and how the clock, stamina, levels, lessons and dialogue choices unlock them.

Index69 scenesUpdated 2026-10-05

This page lists every scene in the gallery of NTR Lesson (version 1.9.2, with the DLC). The gallery has 69 scenes: 49 sex scenes and endings, 4 story cutscenes, and 16 DLC scenes.

You play Hiroshi, a science teacher. Your niece Yui moves into your house, and you give her private lessons. Your son Shin's girlfriend Kaede lives next door with her mother Taeko. Later you meet Rena, a classmate of Kaede and Shin, and Aoi, a student you tutor at the bookstore.

Each section below matches one guide. That guide tells you how to see each scene in the section.

The names in code style, for example flag YuiLevel, are internal game variables (flags). You do not need them to play. They are listed so the rules can be verified and so advanced readers can cross-check them.

How a scene starts

Most scenes follow the same steps.

  1. Find the heroine at the right place, day and hour. Each heroine follows a schedule. Some evening places come from a random roll.
  2. Click her. Most scenes check your stamina here. They need at least 15, and lessons need 20.
  3. Choose the right line in the dialogue. A line can have a condition, usually a level. If you do not meet it, the line does not show or does not lead on.
  4. The scene plays. The game saves its name, and its gallery tile opens.

Many scenes start in other ways: at the end of another scene (a new choice when the scene ends), in the break time after a lesson, or after a won minigame. The guides say which.

Levels and love points

Yui, Kaede, Aoi, Taeko, Rena and Sakura (DLC) each have a level from 1 to 5. The levels are flags YuiLevel / KaedeLevel / AoiLevel / TaekoLevel / RenaLevel, and flag SakuraLoveLevel for Sakura. A level comes from love points: level 2 at 100 points, then one more level for every 100 points, up to level 5 at 400.

Love points come from won minigames. A won lesson gives 25 points, plus 4 for each orgasm, times a bonus from items. Rena's chase and Taeko's harass minigame work in a similar way. Most scenes need level 3 to 5.

Time

The game uses a 24-hour clock. This guide writes hours as 06:00, 14:00 and so on. A range such as "20:00 to 21:00" means from 20:00 until just before 21:00.

The day has five parts: morning (06:00 to 12:00), afternoon (12:00 to 16:00), evening (16:00 to 19:00), night (19:00 to 24:00) and late night (00:00 to 06:00). The world map opens some places only at some hours:

  • The bookstore is open before 16:00.
  • The park and the school have a day version (06:00 to 19:00) and a night version.
  • Aoi's apartment needs the item "Apartment Key". It opens by day from 06:00 to 16:00, and by night from 00:00 to 06:00.

A new game starts in May. 19 May (a Sunday) has its own schedule for some heroines. The story ends on 2 July. See Story and Endings.

Story progress

The main story moves in steps from 2 to 6. Many scenes need a step. For example, Kaede comes to your house only from step 3, and Rena from step 5. See Story and Endings for what raises each step.

Lessons and break time

You give lessons to Yui and Kaede in your study room on weekdays from 16:00 to 20:00, and to Aoi at the bookstore in the morning. Each lesson needs stamina of at least 20. A lesson with Yui or Kaede costs 20 stamina and has two minigames, and you must win both. Aoi's lesson is one minigame. After a won lesson with Yui or Kaede, a break time starts: you can walk around the house, and she waits in one room. Several scenes play only in a break time. See Yui and Kaede. In the DLC, on a day when you cancel Yui's class at the store, neither Yui nor Kaede is in the study room in the afternoon.

Items

Some scenes need an item in your bag: "Sleeping Pill", "Mastering Multitasking" (for lessons with Kaede and Yui together), "Apartment Key" and the book "Physics for Scientists and Engineers" (for Aoi's lessons). This guide does not trace where the game sells or gives each item.

What this guide does not trace

  • How each minigame decides a win.
  • Where the game gives each item, and what a gift to Taeko does.
  • A few local values that some scenes check. The scene entries name them.
  • Where the game checks the item "Sato Family's Master Key".
