Yk how in canon Eli's always clinging to Luka? And Luka being the softie he is always letting it be? Now I'm thinking of a very fluffy prompt, imagine Luka being high on painkillers. Like so high he is barely conscious, maybe the pain was too much and Leo gave him an anaesthetic instead.
Now imagine Eszett visiting him after he's awake, and as soon as they're within an arms reach Luka just, dives straight into Eli's arms and just smiles and starts giggling, 'Eli~'
Cue everyone being shocked beyond words (even Narke is staring dumbfounded) and Eli too was frozen in shock before the absolute exhilaration overcame it and he's laughing so hard and hugging Luka back (but gently so his injuries don't hurt), and Eli's asking, 'Luka~ what's up with you today?' and Luka just, pokes his head up from the embrace and smiles so bashfully that everyone is shocked for a different reason now. Never before had they seen Luka, the always stoic and brusque man smile so shyly, so innocently.
Imagine Leo being jealous on the side going 'what are you even doing...' and Luka grabbing his arm knowingly and laughing, 'leo, are you worried~?'
And Leo's baffled but Luka just pulls him closer and hugs the stiff man lightly, 'dont worry, i respect you the most.'
And while Leo is standing with his mouth agape Eli is wheezing his lungs out in the background and Narke is toppled over him doing the same, while Ulrike is just gasping both simultaneously pleased and terrified. And Heike's just standing aside replaying Luka's smile in his mind, while Julia walks over to Luka and is like 'Luka! Hug me as well!'
And when Luka actually goes to hug him everyone bursts out in laughter while Leo is just, still too dazed to process anything at all.
Imagine all of them gathering around Luka in that rare moment of seeing his unrestrained self, and they're asking all sorts of silly questions, Eli simply repeating 'Luka do you like me?' and Luka's so innocently replying back every time 'ofc i love you!' and when Eli laughs pleasantly Luka too laughs with him just watching Eli and God none of them can deny how absolutely endearing their deputy leader looks at that moment.
And Narke's slumping over Luka's shoulder imitating Eli, 'Luka, what about me~?' and Luka just ruffles his hair and smiles at him and the next moment everyone just starts competing at who can get the prettiest smile from Luka and they're all so enamored and thrilled.
Till eventually Leo has to kick them all out because Luka wasn't doing good, he was just happy because he saw his friends. And when there's only him and Luka left Leo is standing beside hesitantly and Luka watches him and tilts his head, 'Leo', he says and smiles in a way Leo had never seen before, 'i love you as well.' and then he's just, quiet and staring at Luka's expression and his softened eyes. In the end he manages to say nothing and only ruffles Luka's hair, which somehow gets him such an adorable giggle out of the latter that he's frozen stiff again.
Ofc, the next time Luka wakes up back to his usual self, not a single soul of Eszett tells him anything. Except that they're smiling so unusually at him every time now that he has no idea what went down while he was asleep. (He really could've found out what happened but he didn't want to think too deeply just about his friends' smiles, so he simply lets it be)
