Thanks for the nice comment!
And you found a "bug". I simply forgot to put the unlock code for that entry into the VN! I'll fix it whenever we push our next update (there are some other small things we want to change).
The entry in question is about Emma's calming technique! It reads:
"The 5-4-3-2-1 technique is a way to ground yourself when overcome by anxiety. There are variations that involve all five senses while some switch back and forth between only a select set of senses. For Emma's version, she counts five things she can see, then five things she can hear. Next, she goes back to her sense of sight, counting four things she can see, followed by four more things she can hear. This repeats until she counts a single thing each. Between rounds, the same object may be counted - this isn't a competition, it's not supposed to be stressful to come up with items to count."
Thanks for finding that issue :)
