The Quintessential Quintuplets – Memories of a Quintessential Summer – Walkthrough & Guide

The Quintessential Quintuplets – Memories of a Quintessential Summer (Go-toubun no Hanayome ∬ ~Natsu no Omoide mo Go-toubun~) is a visual novel with 14 endings, split over 7 routes.

Memories of a Quintessential Summer is split between a gameplay portion and a more standard visual novel portion. This guide and walkthrough will explain both parts.

Surviving and Studying Tips

In The Quintessential Quintuplets – Memories of a Quintessential Summer, you need to manage the quintuplet’s schedules to both survive and study. In addition, you need to raise the intimacy score for the heroine whose route you are aiming for in most cases.

All quintuplets must have at least a score of 60 in all subjects by Day 14 (3 days remaining). If even one score is below 60, it will result in a game over. Scores decrease as well as increase when studying, so be careful of this.

You can increase their scores in subjects by scheduling studying. If you assign Futaro to support a quintuplet, the scores will increase more and it will raise their intimacy with him.

Gathering food is also necessary. This is simple as long as you reference current food stocks while choosing what food to replenish and when choosing what to cook. Nino never fails when cooking, so I suggest choosing the quintuplet whose route you are aiming for to cook the morning meal, Miku for the midday meal (as she has the second highest initial cooking skill), and Nino for the evening meal. Choosing a quintuplet to cook raises intimacy with them slightly, as well as raising their cooking skill.

Eating food replenishes HP and Mood. If this dips below a certain level, collapsing is possible. You can instead schedule Break (HP) and Free Time (Mood) to fully restore these.

At the end of Day 5 and Day 8, all quintuplets get a free full mood recovery so you may wish to take advantage of this.

Missing CGs

CGs in The Quintessential Quintuplets – Memories of a Quintessential Summer are unlocked both in the common route and heroine routes. If you’ve completed all routes and all endings, then you may have missed some of the common route scenes that only occur if you have the highest intimacy with a certain quintuplet at a certain time or the scenes listed for that quintuplet as indicated in the common route walkthrough below. These can be unlocked by playing through again, ignoring all but one quintuplet, and making sure to select their choices in the scenes as described below.

In addition, I have run into a problem where CG unlocks didn’t save. I found that recompleting these and making a save file afterward worked to unlock them in the gallery.

Steam Achievements Not Unlocking?

Common Route Walkthrough

Through the common route of The Quintessential Quintuplets – Memories of a Quintessential Summer, there are occasional choices. Some of them don’t matter, but some boost intimacy, which will bring you closer to your desired ending

Which of these scenes appear depends on your current intimacy with the quintuplets in the scene. As they can involve two quintuplets, it won’t necessarily be the quintuplet with the highest intimacy. As an example, if you have high intimacy with Miku, and low with Yotsuba, you may not get the scene featuring both of them, but instead get a scene featuring Nino if you have the correct level of intimacy with her.

While you don’t need to get all these scenes to access the route for a certain quintuplet, they are major intimacy boosts if you make the right choices and some contain CGs.

The below lists these scenes and the choices to boost intimacy for a quintuplet:
