Sirius falling in love with Snape's sister was a rather complicated plot. In HP Doujinshi, Sirius and Lily's emotional entanglements often appeared, and Snape's sister, Pupu, often appeared in the story.
Pupu was a strong and independent girl. She had a special relationship with Snape. Although she did not like Harry Potter, she had deep feelings for Sirius. In some novels, the relationship between Sirius and Poop developed so quickly that it even exceeded the distance between them.
In other novels, however, the relationship between Sirius and Poop was not explicitly expressed. The relationship between them may lead to some complicated emotional entanglements and ethical issues that readers need to think about and judge for themselves.

Snape could be very sarcastic and cold at first. He might taunt Harry about finally coming to him for help. However, as he realizes the gravity of the situation, he could start to take it more seriously and actually use his skills and knowledge to help Harry.

He would likely be very strict with Harry, as he is with all his students, but also secretly keep an eye on him to make sure he's safe.

However, as he observes Hermione more closely and realizes the genuineness of her situation, his attitude could gradually change to one of reluctant assistance. He might even offer some words of wisdom, albeit in his typical sarcastic way, to help Hermione regain her strength.
