Short spoiler : Still not reaching truth, that one asmr situation IRL, Hiba belly button, to hotel or not to hotel
Long spoiler : As one would expected, Naoto went easy on Luna's arm, and now it's Hiba's turn to get judokarate chopped on the head. Luna tells Naoto that now is his chance to get back at Hiba, but he plans to go easy on her too. Just as he smacks Hiba on the head, Luna pokes Naoto on his side, and that causes Naoto to bring his hand down with some force. Naoto, possibly afraid of retaliation, gingerly asks Hiba if she's okay. She just laughed, told him that he got her good, and that she'll get some water to cool off. Hiba once again saying that Naoto's chop was really effective, with an expression that's either her awakening into an M, or the chop just sobered her up.
On to the main dish, Naoto's turn. Turns out, the "Deluxe" punishment was actually an "anything goes" punishment, and Luna tells Hiba what she's gonna do to Naoto. Hiba spares Naoto the forehead flick, much to his relief, then Luna sits on his lap.
Luna, still sitting on Naoto's lap, asks if he knows what a "little drink kiss" is while holding a mini bottle of liquor, a "little drink". Naoto, only getting the 'kiss' part, had Luna explain to him that the weren't actually going to kiss. Hiba takes his back for the double-team in exchange for sparing Naoto the forehead flick, and Luna removes the cap and puts the bottle in her mouth.
Luna then starts to pour the drink directly into Naoto's mouth. Luna is clearly enjoying herself, and Hiba starts rubbing Naoto's ear. She mentions learning from Luna that Naoto's weak on his ears, and should Naoto spill the drink, they'll have to do another bottle. Hiba continues to rub Naoto's ear until Luna drops the bottle and bites Naoto's left ear. Right immediately, Hiba follows up by licking Naoto's right ear. After a while, Luna tells Naoto that he can drink now, and Naoto gulps. Naoto thinks the drink was too intense, giving the same expression as that time Hiba blew second-hand smoke directly into his mouth, then Luna asks him if he wants another round.
And multiple rounds they went, Naoto faced down with a few more empty mini bottles on the table. The two leave the bar, and Naoto starts thinking how the present day might have been him just dreaming, how they shouldn't rush, and how his and Luna's story should proceed slowly. As he's thinking, Luna tells him that she's about to barf. Naoto first thinks of heading back to the bar, but changed his mind. With the nearest train station still a fair bit away, they have to find a place nearby to rest.
Chapter ends with Naoto still holding Luna, facing his possible options, the love hotels nearby.
