I mean, either by kissing him or by pouring the drink in his mouth, she needs to tilt his head, as shown in the chapter.
The neck of the bootle is quite small so it can fully fit in his mouth without spilling the potion and it wouldn't take longer to do it.
Also, kissing someone doesn't make the drink go down easier as he got chocked anyway.
And the physical interaction....... is definitely more if she uses her lips instead of a bottle
What do you think the ML would resist more, drinking a potion or drinking a potion from her mouth? ٩(๑❛ᴗ❛๑)۶

She didn't have her gun, but why did she need to make him drink the potion like that? Why didn't she just empty it in his mouth?? The result would be the exact same! (  ̄□ ̄|||)
I know the author just wanted to, but it doesn't make any sense so it takes me right out of the story.
