Page 16 kinda confuses me... So I guess the implication is that they weren't *trying* to be seen as a couple by the others? They could have fooled me... I thought that ever since Misaki (Yellow) said "those two are definitely going out~" they didn't bother to hide it. Maybe they were trying to pretend that they just randomly met on the beach and flirted a bit? But back at the start of the previous chapter, Daigo approached with the conversational premise that Fudou was dating Desumi. Well, I know they're trying to hide it from the public, but at this point the whole team clearly knew.
