Yeh :D

*he worried and took carefully one of her hands*
"Oh no... please, calm down... just breathe deeply, alright...?"

(AND SO I DID AGAIN!)

"It's me who has to apologize, you were going through a really bad time and I didn't know how to help you, ending by messing this up even more than it was, besides I have no excuse for what I called you- Faded! What's wrong?"
*he splited up a bit to give her some space*

I'VE SEEN AND NOW I DID ASWELL

"Your sadness, that devastating feeling you've been suffering for too long ... I'm came here to erase that-"
*he gave a sudden deep hug to her*

*he pulled out his strings, tying up Faded's soul and approaching her*
"Something yours..."

I'VE JUST REPLIED AGAIN ASWELL! *angry duck noise$*

*that glitchy cloud from his head started to appear again and looked down*
"... that doesn't matter right now Faded, don't worry... but... I've come to erase something..."

(Me too AND YIEH I DID ALREDY!!!)

(I WAS SA- naaah, no probs, it's understandable, also I took too long to reply, sorry)
*he arrived to the exit of the portal, but didn't pass*
"... I... ugh, I screwed it up so bad... I don't know if I should go with her... most probably she hates me now... I said such as horrible things, even knowing she takes that bad... maybe no-
*then, he remembered the conversation with Faded just before it all gone bad, and the thing of never knowing what could've happened if didn't try*
"Tch, what a hypocrite I am... how could said that when I was literally gonna do the wrong thing-?"
*so he exited the portal and stood back again in the void, with a flustered expression*

I WANNA CRY, I'VE BEEN TREMBLING DURING THIS RP. At least yeh I am, n you're here too ^^)

(SRRYYY, I WAS GONNA REPLY, BUT THE PHONE FLIPPED AND LOST THE TEXT ;-; Here I am anyway)

(Ok, and yeh, focusing on Faded at previous rp, she kinda acted like what you said, besides Line also practically never arrives to yell, just turns kinda cutting and devastating, and but also would like to see how Faded would get revenge)
*he fell to his knees grabbing one side of the face as glitched extremely bad: an anxiety attack*
"No, no, no, NO- HHHHNNNGGG-"
*he snarled because the stress as his pupils started to distort*
"WHAT HAVE YOU MADE TO ME?! It's all your fault, you... YOU... I hate this, I hate this, I HATE Y-..."
*then something broke inside him: he wasn't talking about Faded...*
"I HATE YOU!! LOOK WHAT YOU DID YOU SAG OF BROKEN BONES-!! YOU NEED HER, AND EVEN WITHOUT KNOWING HOW TO FEEL, GO THERE AND FIX THE CRAP YOU'VE MADE-"
*he was talking about himself*
"I WAS TRYING TO SAVE HER FROM DEATH, BUT FROM WHO I SHOULD SAVED HER WAS FROM ME, AND NOW I'VE PUSHED HER AWAY-!!"
*he began to run through the tunnel, coming back to where her friend was*

I'm between QnA and PaS XD

(Btw, canonly Line probably wouldn't do that, but I wanted to dramatize it more, sorry about that, but also to highlight a bit that he goes so bad through a friend's death and similars, because with them being his world, he can do literally whatever it's required to take them back)
"WHAT THE FUCK WAS I THINKING WHEN CHOSE TO BEFRIEND ANOTHER MULTIVERSAL MISTAKE-?"
*He was talking to himself inside the portal's tunnel, he enlarged the distance to let himself some time to think, he couldn't even speak well because the interferences, then he stopped walking*
"But now the problem is... why do I feel so SICK with that..."
*he couldn't take out what'd just happened from his head, as his hands started to tremble slightly and his breath becoming heavier*

"Heh, predictable"
*when fully entered to the portal, he suddenly turned around*
"Oh, btw, I forgor to say... DON'T. TOUCH. ME. I. HAVE. AN. OBVIOUS. HAPHEPHOBIA. YOU. ANOMALY."
*his voice sounded more glitched than ever, then he turned forward again and disappeared through the portal, as it started to close*

*his expression stayed the same, but he got static for a few seconds, but then, his eyes turned black and his smile turned extremely creepy*
"Heh, yup, I'm a creep, one that should've been dead a really long time, so, as there's still a bit at least of caring for you, I'm gonna get rid of myself for you..."
*he continued smiling, as started to entry in the portal, slowly walking backwards*
"And if I die somehow at any point of the way? Well, I'll disappear from your memories, like if we've never met"

*sighed*
"It's just a suggestion... or maybe a prevention- I'll speak clear: if you die, you'll NEVER have the chance again to see if you could have changed something by trying moving forward, but I'm completely agree with you: is your own life..."
*he opened a portal*
"Better to not keep messing up here anymore, see you later"
*he entered the portal with a mix of an annoyed and disappointed look, mumbling things like "what the fuck I was thinking when coming here in first place?", "this is why I consider some prompts as anomalies" or "it was just supposed to watch, not fucking interact" mixed with glitched snarls*

"As rough as it can seem, it's part of life, and the most sucking point is when you must face situations like this, but it's at your will the chance to go through that... but that can't avoid me to be sorry for you..."
