Derek

2 weeks ago before the anniversary of Stiles and Derek, Derek Hale made a visit to the Sheriff of Beacon Hills. It was in this visit that Derek asked John Stilinski for his blessing to marry Stiles. As expected John couldn't refuse his son's happiness and he rather like Derek and trusted him to take care of Stiles, his answer was a definite yes. After Derek left from the Sheriff's house he could not keep the smile off his face the whole day, he even stopped to get Chinese for dinner before going home. Stiles must've been confused that day when he asked what he occasion was to which Derek shrugged off and told him he just had a good day at work.

He would have to wait 2 more week to propose to Stiles and it would be an agonizing wait but Stiles was more than worth it.

Derek
( Present - time )

Today was the day, the day he would propose to the love of his life. He needed to get out of the house quickly this morning otherwise he wouldn't let Stiles leave their bed which would lead to Stiles interrogating him for answers to which Derek would succumb to his insistent begging and the 2 weeks of waiting would've been for nothing, not to mention the proposal would lose its romantic element that he knew Stiles was a stickler for. He hated lying to him but he couldn't risk Stiles finding out before the time came so he was out of there like a bat out of hell before he could ruin anything.

Derek made a detour from his usual commute to his job, like he would work on a day like today . No there was someone he had to see first before he got things ready for tonight.

When he walks into Lydia Martin's personal office he's met with a surprised expression on Lydia's face and the fresh lingering scent of Stiles. " Derek ? " she says in disbelief. " What are you doing here I thought you were supposed to be at work?" She continues. " I took today off, asked for it weeks ago its my anniversary " he explains and suddenly pauses. "Speaking of which, Stiles was here recently his scent is still here, I thought he went to work?" He wonders aloud. "He was here, some days Stiles buys me a coffee and drops it off on his way to work" Derek hears no lie as she explains and he vaguely remembers Stiles telling him that he had to rush to get Lydia her coffee before she attacks one of her coworkers some morning so he nods.

" So Derek what can I do for you today?" Lydia asks. "I need a favor" he tells her. " And what would that be?" She tilts her head curious now. " I need you to keep Stiles busy" he says. " What?" She says confused. " When Stiles gets off work I need you to keep him away from the house until 6:30" he explains. " Why?" She says slowly, suspicious. " Because I'm going to propose to Stiles and I want to surprise him" Derek reveals. Lydia's eyes widen and she pales "what?" She chokes out. " I'm going to ask Stiles to marry me" he clarifies. "Tonight?" She says. "Yes?" It was Derek's turn to be confused why was she acting this way? " What is it?" He asks. She laughs suddenly " Nothing let's just say that Stiles will definitely be surprised" she says finally. Derek relaxes at her amusement " So... Do you think you can handle Stiles for the until 6:30 ? " he asks hopefully with a small smile. "Oh I think I can manage" and the banshee grins back at him.
