Mystic Messenger: how to get on Yoosung route walkthrough – Prologue, Day 1, 2, 3 and 4 (Casual Story mode)

Guide by Staff Contributor

Published on Oct. 5, 2017

A Mystic Messenger Yoosung walkthrough will ensure you gather the maximum possible hearts from the naive college student and LOLOL warrior.

This Mystic Messenger guide page is devoted to providing a guaranteed walkthrough to Yoosung route on Casual Story's Day 1 through 4.

We haven’t listed every possible Mystic Messenger chat here; there are plenty of others to participate in during Days 1 through 4, but they don’t contain opportunities to earn hearts for Yoosung's route. These ones do.

You don’t need to hit up every chat we’ve listed here to unlock the Yoosung route, so don’t worry about the ones that turn up while you're alseepe. If you are going to spend HG and unlock missed chats, though, you can see which ones are important at a glance. In general, the longer a chat is, the more hearts you’ll earn.

Although you should try to participate in other chats besides those listed below, don’t worry too much about making “wrong” choices in those; as long as you spread your hearts around between the other characters, especially putting them into Jumin and 707 as they're unavailable in the Casual Story mode, you won’t alter your ending. Cross reference with our Mystic Messenger chat time schedule to see where email opportunities arise if you want to know which ones are especially worth logging in for.

Check in with our Mystic Messenger Yoosung route walkthrough and endings page for detailed help for the latter half of the game, or hit up the Mystic Messenger Yoosung route chat times schedule for a less spoiler-filled guide. Need even more help with Yoosung? Visit our Mystic Messenger Yoosung character hub for additional tips related to the cheerful and thoughtful student.

Please note that the Yoosung route is only available in Casual Story mode.
