Ooh, a Bosshi Vanilla release? Nice.
What a kid, running away when she declared she would be his wife. What you do in that situation is nod and say yes, and then in the future, work towards making it a reality! But well, it took a damn long time, but at least he finally told her what actually happened was that he ran away because he was happy.
Hmm...She's a bit of a slut though, I guess. It's established on page 1 that she's someone who likes to fool around, and she even tells him she has a lot of 'boyfriends' (probably her way of saying sex friends) but not a proper lover boyfriend.
But hey, he still loves her despite that and is willing to accept her, and he was super happy that she wants to marry him even after all this time that he...ran away again. Well, it was a nice ending though.
