hello!
i think child at heart is a really good name and bakudeku would fit really well. i think it should be about class 1a going on a holiday and they have roommates at their hotel; bakudeku got paired up. they constantly have squabbles but realise that because of them, they fell in love. it would be nice if there was some angst like lov attacking and some people die, or someone else falling in love with either of them and trying to break them up, etc. it would add a nice twist.
if you need any help with writing i can always send a bit through here and then you can copy and paste it in the story.
i'm sure the outcome will be great!
