My Dress-Up Darling volume 3 - Shinichi Fukuda

 So who was that soaked girl Gramps let inside the house at the end of volume 2?

She is none other then Sajuna Inui, aka JuJu-san, a famous cosplayer and idol of Marin.

And she gets to meet Gojo when she comes out of the shower at his house.  She has sought him out as she saw his costume for Marin, and wants to commission one of her own, amazed by the fact that that was his very first efforts at making one. 

Marin, totally star-struck, convinces her to do a group shoot, meaning poor Gojo now needs to create no less then two costumes instead.  He goes over to her house to discuss the project, which she sees as a home-date, as she is totally falling for the silent introvert, even doing an effort to cook for him.

Later on, they meet with Sajuna and her (very big) little sister Shinju, who does the photography of JuJu, and she teaches Marin and Gojo of the tricks and twists of photography, as they go an look for a set to do the shoot.  They settle on an abandoned hospital, which actually unsettles JuJu quite a bit.

But school also has to be done, so after the exams at the start of the summer break, Marin takes Gojo to the oceanside, which he confesses is the first time he's been there.  Marin pledges to take him to more places he never visited... by just the two to them.

The romance continues to grow in this volume, and it remains a great romcom slice of life anime to read.  Onwards to the next volume now!
