My Bodyguard, My Love (BlackPink Lisa x female reader)

Period

The next day
Ma and Lisa is laying down on my bed. Suddenly we heard someone knocking on the door. Lisa went and open to see Jisoo, Jennie, Rose, Yuri and Yuna,  dressed up.
Me: why are you guys dressed up? Are you guys going somewhere?
Jennie: don't you guys remember? We are going to buy groceries. We told you yesterday right?
Me: oh sorry we forgot. Wait a minute. We'll come in 15 minutes.
Rose: you guys better get ready fast.
We nodded as we closed the door and we wear our outfit.

Lisa's outfit:

Yn's outfit:

( Note: Lisa's clothes are already moved into Yn's room.)
After getting ready, we went to the Living room and saw everyone waiting for us. We then we to our van and got in it then drove to the grocery store with so many bodyguards.
Lisa's POV
We were shopping. Argh!! My stomach ache so bad from the morning.
Yn's POV
A guard was pushing the trolley when I saw red stain on Lisa's pant. I went behind her while removing my jacket and tied it around here.
Lisa: what are you doing?
She asked confused.
Me: are you on your period?
Her eyes widened.
Lisa: oh God I forgot.
I turned to Yuri and told the situation as she nods and told it to BlackPink.
Me: I will take her to the van.
They all nodded as I picked Lisa up in bridal style and went to the van, followed by 2 bodyguards. A bodyguard opened the door of the van as I placed Lisa down on the seat. I got inside the van.
Me: I'll go get you paid and something to eat and drink.
She nodded before she put her head on the seat. I got off the van and went back into the shop. With some worker's help, I went to the aisle where the pad and tampons are placed. I started searching for some pads.
Me: wait I don't know her size. Aish!! What am I gonna do?
I took all the sizes they had and went to the cashier. The cashier took all the pads and started scanning them.
Cashier: it'll be $30 please.
I nodded and took my wallet, which is mens wallet and took my black card and gave it to the cashier. She took it and swipe the card and gave it back to me. I put it in the wallet and put it in my back pocket. I took the bag with the pads and went to the van and gave the bag to Lisa as she looked at me confused.
Me: I- I didn't know your size. So~~~ I took every size.
I said as I looked down embarrassed. She chuckled.
Lisa: thank You.
I nodded, not knowing how got respond. I then took a bag and took out a pant from it and gave it to her. I closed the door of the van as she changed. Then I went to a nearby cafe. I brought two strawberry milk tea boba and macarons. After paying I went to the van and saw Lisa already changed. I opened the door and got in and again closed it. We sat at the back.
Me: how are you feeling?
Lisa: good.
Me: here let's eat.
She nodded and took the macarons and boba tea out.
Lisa: how did you know my favorite is strawberry milk tea boba and macarons?
Me: I didn't know. I just guessed. Also that's my favorite too.
Lisa: thank you baby.
She said and smiled at me. We then started eating.
Our food:

After awhile they came back from shopping as we went back to our dorm. Yuri and Yuna went to this house on the way.
