"Jeno-ssi, I'm fine!" You insisted. "It's not like I'm sick or anything."
Yet, escaping his grasp proved futile. Your objections gradually faded as he gently laid you on his bed.
"We're going to rest here," He declared, settling beside you. "And you're not going to think about school."
A resigned sigh slipped past your lips, fully aware that there was no point in fighting him on this. Jeno knew how you hated to leave things like work off to the side. But he just couldn't stand to watch you in pain. 
"I think you're just using my period as an excuse to cuddle," You mumbled with a slight pout. 
"Maybe a little?" 
Your boyfriend's nose nestled into the crook of your neck. His sturdy arms enveloped your waist securely, while one hand tenderly massaged your lower abdomen, where the cramps were bothering you.
Gradually, discomfort and concerns retreated to the background. Ironically, Jeno grew even more affectionate during your period. But you really couldn't complain.

HAECHAN
Initially, the experience was a little weird for Haechan. He felt sort of bad that you had to go through this monthly ordeal, and he couldn't really do anything about it. Luckily, you managed to maintain a relatively steady demeanor during your period, which alleviated some of his concerns. While the occasional cramps were bothersome, your overall mood didn't undergo drastic changes, at least not visibly.
During these times, you found yourself grappling with intense emotional surges that deviated from your usual disposition. They were something you couldn't exactly control and you hated it. Because of that, you tried to stay away from Haechan and deal with things on your own.
Eventually, Haechan would catch on to this and convince you to open up to him. You told him about your tendency to internalize your emotions, which made him feel terrible. While he was an expressive person, you struggled to share how you felt. But once he was more aware, the signs became a lot clearer and he knew what to look out for. 
"You know I'm always here for you, Jagiya," He'd often remind you. You would be sitting at the end of the sofa together, as he spoke softly. "You can cry if you want to, or yell if you're upset about something. You don't have to hold it all in when you're with me."
Hearing him say this would make you feel so grateful. He was quick to gently wipe the first tear that fell. "I don't want to be a burden to you," You admitted. 
He would let out a sad chuckle in response. "Believe me babe when I say that you're never a burden to me."
Haechan's embrace tightened around you, enveloping you in a reassuring warmth. "You love me at my worst, and I'll do the same for you."
You seriously could not ask for a sweeter boyfriend than Lee Donghyuck.

JAEMIN
You were coming back to the Dream dorm after a lunch date with Jaemin. As you both entered and removed your shoes, a soft gasp escaped your lips. He was about to ask if you were okay before you quickly excused yourself to the bathroom.
Even though you didn't say anything, he picked up on the situation pretty fast. Being the thoughtful boyfriend he was, Jaemin had become a total pro when your time of the month came. While you rarely complained much about such times, he still took it upon himself to pamper and care for you during this phase.
