Masozi does not really feel like Wen Ning's response here was encouraging! ...Also there are confusing and maybe concerning things happening nearby!!! 

"- Wei Wuxian? Are you okay?" 

(Meanwhile he is snuggling up against Wen Ning and rubbing his back in small circles.) 

WEI YING MIGHT NOT BE OKAY?????? HE WILL HIT SOMEONE WITH BICHEN!

"Don't worry, Zaizai, I'm fine. I'm going to make fun of Lan Wangji so much for this in the morning. So. Kissing or math?"

"....I dunno? I'd want to do one math and then kissing but maybe I'm the only one here who wants math?"

"I want math! I always want math."

"I want math. Wei Ying likes math."

"See. There we go. You have a three liter jug and a five liter jug and an unlimited supply of water, how do you measure exactly four liters?"

Masozi spends a while considering this, lifting both hands and gesturing vaguely as a thinking-aid. 

"I - if you filled the three-liter jug and poured it into the five-liter jug and then filled it again...no that'd be six not four - if you filled the five-liter and poured it into the three-liter and let the rest spill, and then filled the five-liter again....that'd be eight... Half of eight is four but I dunno how you'd get half, if you don't have a bigger jug you can pour out half of...." 

- apparently he is still too drunk to do math??? 

He is going to kiss Wen Ning instead, even though he's probably very bad at kissing. 

This is very wet and not very pleasant and he really preferred the leaning????

....Yeah this isn't very enjoyable. Maybe it would be better if he were good at it, but it's not like he has any practice so how could he be. 

Masozi backs off. 

".....Sorry! Wen Ning, I - I don't think you should think you don't like kissing if you didn't like that, 'cause I'm not a very good kisser?" 

He will go back to snuggling. Snuggling is much easier. 

Yes. Snuggling is nice. He likes snuggling.

Everyone's distracted so maybe he can lick Nie Huaisang's neck a little bit.

Whimper.

"Okay, so, you're on the right track with the jug problem-- it might help to think about it in a more abstract way? You're adding and subtracting threes and fives and you need to get to four."

"Oh! Five plus five is ten! And three plus three is six! And ten minus six is four!!!!"

Delighted wiggle. 

"- I still dunno how you actually do that if you just have the two jugs though." 

"Right-- you've sort of got one five and one three at a time? If that makes sense."

He is following none of this but his Wei Ying is SO smart.

This problem is NOT FAIR to give him when he is DRUNK. 

"...Okay so. Five is one more than four, and three is one less. You...could pour the five into the three and stop once the three was full? ...But that'd still be just five total. Since you'd have the three full and the five with two left. ...Can I get any more materials for this? This is math world so there should be as many materials as I want?" 

"Nope! Only two jugs. You're on the right track, though. So you have your two, what can you do with your two?"

Aaaaaughhh. 

"- I tried to think of it but I couldn't!"

Masozi is pretty sure that he COULD figure it out if he weren't DRUNK, however. 

"...If I fight you and win will you tell me the answer." 

"NO fight Wei Ying!" he says in English, enunciating clearly so he can be understood.

.......Apparently he is missing even more context than he realized? 

Oh no, Lan Wangji doesn't speak English and so he...needs to say things in Mandarin...?

He doesn't actually know the word for 'fight' in Mandarin?

He does know the words for 'learn' and 'work' and 'you'. And so he can....probably say most of an entire sentence, if he includes some miming by lifting his fists? About how he would be delighted to fight anyone including Lan Wangji? 

Lan Wangji has NO idea what is going on! Is Masozi threatening Wei Ying? Lan Wangji will FIGHT him.

Masozi can't threaten anyone if he has been PUNCHED IN THE STOMACH.
