Dude got balls to confess his love on the very first day

 

[obsidianpassion]

@KAFi That is due to the history they had, they made the promise and as a pure child he held to that as absolute truth. I applaud such manly balls, I do not know why she would even refuse to acknowledge their history, especially after talking about having precious memories, lol.
