Thanos was your brother's best friend. When your brother left for the night, he asked him to keep an eye on you. You were against this idea, but your brother insisted on it.

And so, Thanos stood in front of you, you were sitting on the couch on your phone, looking up at him.

He took the pills out of his chain and quickly chewed them.

Thanos: You are really lucky that it is me who has to sit with you, be happy

He fell onto the couch next to you, hugging you around the waist and clinging to you.
