Mayhaps some Kasumi, Yukina, and Ran OT3 headcanons?
• Getting Ran and Yukina to call each other by their first names without the formalities was one of the biggest problems Kasumi had ever faced since they first started dating. It really frustrated her to no end, especially with Ran refusing to cooperate. Two hours later, they started calling each other by personally made nicknames. Kasumi calls Yukina “Yuki-chan” and Ran “Ranran”. Yukina calls Ran “Ran-chan” (while getting all flustered) and Kasumi “Kasumi-chan”. Ran calls Yukina “Yuki-san” and Kasumi “Kasu-chii” (she got infected with Moca calling her that)
• They look like those actual serious trios (especially with Yukina and Ran in the picture) but in reality, Ran is the one always getting worked up at Kasumi’s (and sometimes Yukina’s as well) stupid mistakes while Yukina spoils her (Kasumi).
• There’s at least one day in the week when they’d walk to school together. But on a daily basis, Yukina and Ran would pick Kasumi up (as they noticed that Haneoka dismisses them earlier than Hanasakigawa) and from there, they’d walk to CiRCLE or basically just anywhere together. The rest of the bands don’t really mind, honestly.
• They’re so clingy to one another. There was a time when Yukina and her family went on a road trip and all she (Yukina) ever did was talk to her girlfriends via group chat. But she still couldn’t help but miss them so much. That’s why, much to Ran and Kasumi’s surprise, Yukina finally returned to them, crying, saying that she misses them so much. (They all cried in the end anyways)
• That’s why it’s kind of hard to separate them. They’ve become each other’s support teams and whatnot that they couldn’t imagine what it’d be like to live without them for more than three days.
• Yukina and Ran really do everything just for Kasumi to rest. After hearing from Arisa what overexhaustion got her, they made a ton of plans that involve getting Kasumi to sleep, most of them being back-ups because they know how she isn’t the type to cooperate.
• But when she succeeds in exhausting herself, she ends up getting sick. Yukina and Ran become those angry gfs who give her so much care, love, and affection. Kasumi doesn’t mind, though.
• Yukina tried to learn how to play the guitar for her gfs. But she hid it so well that Kasumi and Ran already figured it out when Yukina’s fingers started getting injuries. They ended up buying a guitar for Yukina and even helped in teaching her how to play it.
• For Valentine’s day, Ran arranged two sets of flowers, each representing her girlfriend. Yukina and Kasumi felt so touched that they always make sure that their flowers stay alive.
• Yukina, the tea gf. Ran, the coffee gf. Kasumi, the juice gf.
• When one leaves, the other two just cuddle until she comes back. They’d end up making a cuddle party of some sorts.
• They usually have their sleepovers in Kasumi’s room. However, they become so frequent that they ended up making a schedule on who sleeps in the middle.
• They’re a very domestic trio. Kasumi is in charge of laundry and cooking. Yukina cleans the place and tends to their cat. Ran decorates the place and does the groceries.
• Their relationship helped Yukina and Ran become more open when it comes to their feelings. They honestly couldn’t thank Kasumi enough.
• Their communication is so strong that they don’t even need words to know what’s going on in one of their gfs’ minds.
• Really, they probably won’t break up in a million years with all their fights. They want things to stay the way as it is and do everything to prevent their relationship from falling apart.
• Personal headcanon: definitely a comfort ship
(And that’s why YukiRanSumi is my OT3 thank you for coming to my TED talk)
