Whenever Iwaizumi is on the phone with Oikawa he let his smile form on his lips, softly laughing at how dorky and cute his boyfriend is cause "its not like he can see it anyway"

But actually Oikawa can hear Iwaizumi's small laughs and that makes him so happy

And that is why he prefer to phone call Iwaizumi than texting him

If you're expecting for a phone seccs stuff I'm sry to pop ur bubbles but I'll consider doing it next time ( ͡° ͜ʖ ͡°)
