A girl suddenly bursting into a guy's room late at night is definitely something worth noting under normal circumstances, as it could lead to scenes not suitable for children at any moment.
Unfortunately, when similar incidents occur to Leon and Tassera, their relationship is anything but ordinary. Having practiced the Inner Core Dual Cultivation Method and having been completely honest with each other, it's just a trivial scene not worth mentioning.
"Why are you here?" Leon, with crossed legs, sat on the bed. "Is something wrong?"
"The night is long, and sleep eludes me," Tassera said in an affected manner.
A girl still has to retain some modesty, of course. Tassera wouldn't admit that she'd been restless after her conversation with Fiora that day.
"You can't sleep, but I can," Leon lay back down. "Aren't you sleeping with Cecilia? If you can't sleep, you can chat with her."
