Nope, the anime and manga are the same, there's not much differences between those two. Actually, I prefer the anime cos the manga has very slow development in relationships.
No, there aren't so many love triangle drama. There is, but not a lot, just enough to make the story interesting.
It's still on-going so I don't know, but I guess the couple is gonna end up with each other
Overall, it is worth watching, ive watched the anime, and totally fallen in love with it However, in my opinion, I think you should just watch the anime, the manga is just ridiculously long and there's not much terrific development between two main characters.
Okay, thank you! I'll definitely watch it now And then, I'll read it, it might fill in a bit of some things I might not understand in the anime ^^
Thank you so much for your reply!
