I believe they are cuddlers

Kisses, they both love fluffy kisses

These two are quite an innocent ship

When Hikaru is sick Aiger always brings him freshly made chicken soup (the only sad people in this situation are the chickens on Aiger's farm)

When Aiger is sick Hikaru makes him lots of treats and sweets to make him feel better

Aiger is a tad bit overprotective

The day someone flirted with Hikaru they left with a injured neck, a broken arm and a serious concussion

Hikaru is the fem boy in this relationship

Aiger is top and Hikaru is bottom

They have training sessions as a excuse to stay together

Wakiya was a bit worried since Aiger got corrupted once but later accepted it when he realised how nice he was now

Low-key, this would be one of the only couples that wouldn't even think of breaking up

Aiger enjoys Hikaru's kisses

OTP. My OTP

Okay, I seriously hate you if you don't ship this

Aiger might have nearly got corrupted once but Hikaru stopped him

The chemistry between these two is perfect

Can't get a single sensible moment together being the only sensible protagonist

Hikaru is a complete Cinnamon

Aiger is kinda like a bad boy

Wakiya always make sure they never get a room together because he gets suspicious when they're alone

Movie nights are their thing

When they started dating Aiger never ate breakfast at home again

He doesn't eat lunch at home either

When Aiger has problems studying Hikaru encourages him the best way he can

For Halloween Hikaru would dresses as a princess or Little Red Riding Hood

For Halloween Aiger would either be a knight or the Big Bad Wolf

Might add more of my thoughts to this but this is all for now
