A good start and an intresting idea.
Hope you continue with the updates

Will SI-Snape meet Lilly? Having Snape without Lilly is just weird even a SI-Snape who have no romantic interest in Lilly they still became good friends with her. So I hope you give us SnapexLilly fluff, I don't care if it's romance or friendship fluff but please give it to me.

As for Hogwarts I hope you put the Marauders in their place. Look I hated the Marauders during their Hogwarts sure we only saw Snape's memories and he beyond bias towards them but they were cruel to him and probably bully most Slytherins during their years at Hogwarts. The Marauders believed that all Slytherins were evil and future death eaters, so they bully them. Which they would never been punish for it which created resentment for their victims believing that the entire system is against them so they join Voldemort in order to change it.

Liking it so far. For the romance I think him corrupting Bellatrix would be great, it would make sense since he would be afraid of betrayal and she's easy to make fanatical and it would give him access to the black family.

P.S. If you don't mind that it's (unfortunately) dropped there's a Snape!Centric fanfic I greatly recommend : Path To Victory - A Severus Snape Story

Huh, I actually remember reading Dio Black‘s Half-Blood Emperor. I was quite sad that the interesting story was left unfinished.
Anyway, your grammar and pacing are good so far. I would recommend to keep challenges in mind for your story - if Sev succeeds too often it can become boring.
Be it some discipline of magic or his relationship with Lily for example, everything should have ups and downs. At least for me the struggle is usually the most gripping part to read.
Since it has been only 10k words so far there is not much more to say at the moment. I do hope you have motivation to write the story you have in your mind to its conclusion no matter how short or long that may end up being.

I enjoyed reading it and am looking forwards to more!

no chapters ?

another chapter nicely done. Hope you update soon.

Looking forward to more

Siempre me pregunto porque la mama de Snape se caso con Tobias. Si pudieras recrear eso estaria bueno.
En mi opinión con Severus, estudiaría quimica y luego ampliaría a anquimia

splendid

how about immortality due to longevity and healing factor like the wolverine and deadpool

one kind of immortality could be clones. severus could have a bunch of clones in stasis on an undetectable satellite in orbit.
witches and wizards can apparate and they don’t leave their souls behind, so maybe some runic sequence could teleport his soul into the clone satellite after a death.
the runic sequence could also immolate his body upon death, as a way to prevent an enemy from looting his body, but also to remove evidence of the runic sequence.
i havent seen any fanfic with that type of immortality before.
also i applaud you for not making your fanfic timeline be during harry potters generation. ive read a great many harry potter fanfictions, and a concerning amount have been identical to cannon with the addition of an extra character or the bashing of a character they didn’t like.
i like your work so far and i hope to see more!

A Severus Snape SI. This was something I wanted to read for a while. Too bad there are only a couple of them.

I just read both chapters and I loved them. Please keep up the good work, this fic is a delight.

As for love interest, although Lily can be smart and sexy, let's remember how she chose James, an annoying bully boy who bully Snape with his group of assholes. Come on, two heirs to two powerful houses and a Dumbledore pawn werewolf. Come on, he abandoned him and chose him over his childhood friend just for an insult that was spoken in the heat of a moment.

Although I have never liked the character of Snape, for me Lily is a real bitch. What could Snape do against James and her gang? We know which side Dumbledore would chose to if things escalated and Snape struck back.

I would go for one of the black sisters for a love interest, but before Severus had a high enough status to have a relationship with them. Severus is close enough to a nice red-haired pussy to fuck in the meantime. Also, if you start early as compunctions, manipulation and legilimency, Severus might as well have his loyal hottie and redhead assistant Pepper Pot **, ehh I mean Lili Evans.

gracias x el capitulo, que se quede con lily

omg what an amazing start! Thank you so much

hello there I recently found your si story and I have to say I really like it and I look forward to seeing what happens next. I also do hope that he can improve his relationship with his mother after his father had that horrific and tragic accident.
