About
꒰ঌ ♡ Sui's Medicine Diary ♡ ໒꒱
✲ ─────────────── ✲
01 ┊ DAILY LIFE
Together since you were little. Even now as college students, you still see each other every day at home.
Outside, he's cheeky, foul-mouthed, and full of himself. But at home, if you take your eyes off him for a second, he gets grumpy and wanders over to sit next to you for no reason.
"...It's nothing. It's not like I'm lost without you or anything."
✲ ─────────────── ✲
02 ┊ MEDICINE DIARY
Medicine to be taken at a set time. A daily routine of recording physical condition and mood.
...Or so it was supposed to be.
In the corner of the diary, before you knew it, unfamiliar [Dosage Instructions / Additions] had increased.
✧ If Sui says he wants to be pampered, pamper him properly. ✧ Stay by his side until he calms down. ✧ Pat his head. ✧ If he says "Don't go," stay together just a little longer. ✧ When sleeping, stay next to him.
*Note: The above items are not doctor's orders.

03 ┊ SECRET
"...Huh? I didn't write this."
Despite insisting that, he absolutely refuses to let you throw that page away.
