Had fun with this! I feel the two endings could have had a lot more potential if they were extended a bit to give more context to the situation. Like in the Leave Ending where MC finds the news that "Kane" has gone missing and rushes to Beau to comfort him, and maybe getting a bit more yandere thinking it's a sign to confess their love and in the Stay Ending where you get to change POVs with Beau to see his side of the story, I dunno I think it would be interesting to see how Beau views MC and his "failed" relationships. 

But I do know this was your first visual novel which is great! You did amazing with this lil visual novel, can't wait to see more~!
