Just to steal it so he can claim what is Alejandro's as his, because he thinks that she stole it, to blackmail her into following him, to torment Alejandro, or do something even more nefarious? What is Diego's motives?
I don't know the reason, I can't understand the raws, I could only look at them, but I think he was jealous or something? Why, I have no idea. He's probably an egotistical bastard that can't stand when an awesome Girl like Ibee isn't falling for him.
This... Is all i got for that cliff? Noooo! I want more! Why can't time go faster...
... But if time goes faster, that means i would die faster too. Hmmm... Nevermind then. Good work for the translators~ I don't want to be some "entitled" reader, but hey, i need to vent this annoyance from the fact that i can't read korean or have the money to actually read it from the source
