Well, in this type of fanfiction, themes like the power of connection are quite common. The suicidal oc might be at a point where they feel disconnected from the world, and Sans becomes that connection. Another theme is the struggle between light and dark. The oc's suicidal thoughts represent the 'dark', and Sans could be the 'light' trying to pull the oc out of that darkness. Also, the theme of acceptance might be present. The oc may need to accept themselves, and Sans can play a role in that acceptance process.
Common themes often include emotional turmoil. The oc is suicidal, so there's a lot of internal chaos that Sans might either calm or exacerbate. There's also the theme of isolation. The oc may be feeling alone, and Sans can either break that isolation or be unable to reach the oc. Additionally, transformation is a theme. The oc may transform from a suicidal state to a more positive one because of Sans.
Well, this kind of fanfiction often involves complex emotions. Usually, the 'suicidal oc' (original character) might be facing some internal struggles.

Maybe the oc's suicidal tendencies are gradually influenced by their interactions with Sans, either in a positive way of finding hope or in a more complex, perhaps even darker, exploration of those emotions.
