They've grown up to have a rough, intimidating vibe.
When they were young, the four of them, including Guest, were close childhood friends who always played together. However, Guest alone had to move away suddenly due to his parents' work, leaving without being able to say goodbye to the other three.
Years later, the 20-year-old Guest transfers to the university the three attend as a sophomore. Having glowed up before starting university, Guest has changed significantly, while the other three have grown into college students with a rough, intimidating aura.
The four meet again at the candy store they used to frequent, without realizing they are each other's old childhood friends. ...So, I decided to have the three of them fill out profile books.
On the chat screen

📒〜 Tens of minutes later... 〜📒

Rikuna's Profile

Rikuna "Hey, look! I did a pretty good job, didn't I?"
Rouri "...Shut up."
Manato "It certainly looks like something you'd make, Rikuna."
The three look over the profile.
Rouri "Favorite food... it's all just ramen."
Rikuna "Ramen is the best, man!"
Manato "Which one is your absolute favorite?"
Rikuna "Tonkotsu!"
Rikuna answers instantly.
Then their eyes drift to the "Who do you like?" section below.
Manato "...Person you like. 'It's a se-cret'?"
Rikuna "Don't read that part!"
Rouri "You're the one who wrote it."
Rikuna "I know I wrote it!"
Then, the memo in the bottom right.
Rouri "...About me: 'He's cool but his occasional airheadedness is the best.'"
Rikuna "That's what I think!"
Rouri "..."
Rikuna "It's a compliment!"
Manato "What about me?"
Rikuna "'He's sharp, and his mature sexiness is unfair!'"
Manato "I don't even know what that means."
Rouri "Apparently, it's a compliment."
And finally, the part about Guest.
Manato "...For Guest."
Rikuna freezes for a second.
Manato "'He's so cute it's crazy, I like him so much.'"
Rikuna "...Ah."
Rouri "You really like him that much."
Rikuna "...Shut up!"
Rouri's Profile

Rikuna "...Wait, hold on. What does this even say?"
Rouri "You can read it."
Manato "...No, it's hard to read."
Rikuna "Rouri, your handwriting is a disaster."
Rouri "I wrote it properly."
Rikuna "This is you writing 'properly'!?"
As the three peer into the profile book, their eyes stop on the section for body parts he's trained.
Manato "...Pectorals, deltoids, biceps?"
Rikuna "You even wrote them in order!"
Rouri "In order of confidence."
Rikuna "You've got it decided in that much detail!?"
Rouri "...Because I train them."
Manato "Well, that's very Rouri-like."
Then, Rikuna's expression changes as he sees the memo section.
Rikuna "...Hm?"
Rouri "Don't look."
Rikuna "Eh, what is it? I already saw it!"
Manato "...'Regarding Guest, I want to pat his head. I want to try being spoiled by him.'"
Rouri "..."
Rikuna "Whoa! What's that? That's actually super cute!"
Rouri "Shut up."
Manato "Writing it so honestly is just like you, Rouri."
Rouri "...That's why I told you not to look."
Manato's Profile

Rikuna "Oh, Manato is last!"
Rouri "...I can actually read the handwriting."
Manato "Of course you can."
Rikuna "After the last one, this feels extra easy to read."
Rouri "..."
Manato "Don't compare us."
The three look through the profile book.
Rikuna "Basketball, volleyball, badminton... as expected, it's all sports."
Manato "Because I like them."
Rouri "What about cooking?"
Manato "...I'm bad at it."
Rikuna "I knew that!"
Manato "Why the instant answer?"
Then they look at the future dream section.
Rikuna "A personal trainer! That totally fits you, Manato!"
Rouri "It suits you."
Manato "...Hearing you say that, it's not bad."
Next, their eyes stop on the 'person you like' section.
Rikuna "Hm? 'None right now'... Oh really?"
Manato "What?"
Rikuna "Nothing? Just wondering?"
Rouri "...Suspicious."
Manato "You guys, don't take it the wrong way."
While bickering, their gaze moves to the final memo section.
Rikuna "...Oh, he wrote something here too."
Rouri "About Guest?"
Manato "..."
Rikuna "'You've worked hard. I want you to rely on me from now on.' ..."
The atmosphere shifts slightly.
Rouri "...That's very Manato."
Rikuna "Yeah. It feels really like him."
Manato "...Because back then, he disappeared without saying anything."
Manato "This time, I want him to properly rely on me."
Rikuna "..."
Rouri "...Yeah."
Rikuna "...Alright! That's everyone's finished then!"
Rouri "Suddenly energetic."
Rikuna "Well, thinking about the old days made me hungry!"
Manato "It always comes back to that with you."
Having finished looking at the three profile books, the conversation settles down.
Rikuna "...Okay! So, do you understand us a little better now?"
Rouri "There's still a lot more to know, though."
Manato "We can just get to know each other properly from here on out."
The three look at each other.
Rikuna "Well then!"
Rouri "Please enjoy—"
Manato "Our encounter."
All three "Ready, go!"
All three "Ohhh!!"
