When and how did he get it?

Len's POV

I got the ingredients of the food I'm making. Hey you don't believe I am a good cook?? Ask Rin
She eats most of my food when we were in middle school. I'd make us both a bento for lunch and we eat it in front of the gardens of the school.
I also got an A+ in cooking class, is that enough proof?

"Um... L-len-kun.. I-i made the sauce for the teriyaki beef.."
I looked at Lenka ' s hands. They were behind her skirt and shaking a bit. Was she nervous?

"Good job. You can go back to your brother. I got it now from here."
I petted Lenka ' s head and continued watching the bacon and cheese sandwich grill.

"A-are you sure? I can assist any possible way I can. Really!"
Lenka started tugging on my shirt and it started to slip a little.
Crap. Not good. She can't see that horrible scar.
I pulled my shirt up and answered with a serious tone.
"I got this now from here. Go check Rinto. I bet he is worried about you."

I saw Lenka look down. She really wants to help, but I don't want her to get hurt from this oil stuff flying toward our faces. Those stuff burn like the flames of hell.

"F-fine.. I'll go."

Lenka slowly walked to the stairs and stopped.
I watched with curiosity. What's up with her?

Soon she started running up the stairs with a shocked face.
Did she see my scar?? I hope not.

Lenka ' s POV

Something looked horrifying on Len-kun... what was it...
I was fooling around with Len-kun but when I tugged on his shirt a little, I saw something that looked really bad. As if something scratched him so hard, it left a scar..
I must ask Rin to see if she knows.

I ran to see Rin putting her Orange panties into her drawers. she must know. She is Len-kun ' s twin. She has to know!

"R-rin.. I have a question.. but we must speak in private. This is serious and I need to know."
I walked into her room and shutted the door silently so no one could hear.

I pushed her into the closet and I kept her quiet.

"W-w..."
I removes my hand from her mouth.
"W-what are you doing?? Was is it you want?? No need to kept it a secret. I'm sure Onii-chan won't tell or care."

"N-no. It's about Len-kun.."

"What? Let me guess.. you wanna know what type of girl he likes?? Tsudere or Kuuder-"

I placed my hand on her mouth again, trying to shut her up.

"N-no! That's not it! I need to ask you this, you probably the only person I can ask."

Rin got a serious look and stopped joking.

"Alright what is it?"

"I-i was pulling on Len-kun's shirt and it fell a little. Then I saw something on his chest. What is it?"
...
...
Rin kept silent. She didn't answer but she kept her eyes hidden with the shadow of her bangs.
"I-it's nothing. You probably just saw a bug. Onii-chan wouldn't hurt a fly unless he had a reason."
Rin started to give me a shocked look, like I did something wrong.

What is that thing on his chest....
