he supposed co-star (Kotono) is a real AV actress, she was spotted by the big tits adult shop's manager and then promptly invited to a bar where the MC and his flat coworker were also invited. she then introduced herself as a former AV actress.
the adult shop's manager thought that AV actress debuted with some criticism, citing her being boring and expressionless but that changed after the DVD where she played with Miyama Yuri. and she said that she was the one who told her to smile more. but after that Miyama retired and practically disappeared even though she thought Miyama was proud of her AV works.
in chapter 7 we see that Kotono tried to greet Miyama again but then she's perplexed because she would've reacted more if she knew her so she thought she's the wrong person
then fast forward to the newest chapter, the 3 girls became friends and decided to come into MC's apartment because they're curious of his porn collection, they then told the manager to go the supermarket to buy stuff only to find Tamagawa on his way home. after knowing the 3 girls were at his place, she also wanted to be invited which made him panic and immediately texted his coworker to hide all the porn somewhere else. while trying to find place to hid it, the coworker found an old photo picrel and then began to think what if MC's obsession with Miyama Yuri is because of her look-alike with the girl in the photo
