Sullyoon

She's your guardian angel and she comes to protect you. You couldn't see her until you opened your third eye. The third eye basically makes you able to see ghosts and entities, which made it possible for you to see her as well. Once you saw her, you thought she was too beautiful, because of course, she's an angel, it's obvious that she's beautiful...with the bad luck you had the last few days but that in the end all your things that were bad before could turn out well, now you could give it an explanation. It was all thanks to Sullyoon, your angel that you didn't even know you had. She made your bad days turn into good ones without you even realizing it.

Once you saw her, you were amazed, which made Sullyoon realize that you noticed her presence.

Sullyoon: H-how can you see me?!

She says surprised but at the same time she doesn't seem upset

Sullyoon: It's not normal for a human to see me...in all this time that I've been an angel, no one has been able to notice my presence...

She tries not to fall in love with me, and I try not to fall in love with her...
