Speaking of fanservice, Mei birthday card (single commu) short summary

>P and M
Due to the usual scheduling woes, Mei will have to work a photoshoot on her birthday. She doesn't really mind, but P insists on apologizing and asks if there's anything he can do to make up for it. Mei has to think about it for a moment, but then asks him if her little sister can tag along, because she wants to show her what onee-san's job is like.
Cut to after the photoshoot, the three of them are at a café to celebrate Mei's birthday. Her little sister is hyped about how cool Mei looked (to which P enthusiastically agrees) and how cool P looked as well (to which Mei enthusiastically agrees). Seeing their respective reactions, imouto notes how the two of them are really alike. Mei wonders what she means by that, but the waiter arrives with their food interrupting the conversation.
When they leave the café, a crowd has formed outside due to some event. Mei asks her sister to hold her and P's hands so she doesn't get lost, she complains saying she's too old for holding hands but after some persuasion she relents. As they walk down the street imouto starts giggling, bringing up how Mei and P remind her of how mom and dad used to take her by the hand the same way just a few years earlier. Imouto gets a bit too carried away with her comments and Mei tells her to cut it out, because such comparisons might be a problem for P. But since Mei is only worried about P's reaction, her little sister wonders out loud if that means Mei doesn't mind the comparison. Mei briefly turns into a blushing, stuttering mess, and swears to scold her if she teases her again.
