I'm not sure who Allison and Twitch specifically are in this context. There could be many people with those names. If they are two ordinary individuals, perhaps they met at a common place like a coffee shop. They might have started as friends, gradually discovered common interests, and then love grew over time through shared experiences and deep conversations.
One good fanfic could be 'The Choice That Changed Everything'. It really delves into Scott's thought process as he makes the decision between Allison and Stiles.
