A Flower in Your Hair - Devilgram
"Prepare to annoy."
After MC and Lucifer have finished the mochi, he's feeling even calmer and tranquil, to the point he feels like nothing could possibly anger him. MC can either tease him that he'll definitely get angry, or tickle him to test his patience, which makes him embarrassed. Once MC stops, Lucifer reflects that cherry blossoms last only for a short while. He puts a few petals into MC's hair, and claims it suits them. He notes that MC might be tired of sitting on the picnic sheet and invites them to lean against him. If they don't, he tells them to at least stretch their legs to avoid cramps. He compares MC to the cherry blossoms - delicate and fleeting, to which MC can ask him for a kiss. He considers planting cherry trees at the House of Lamentation, but drops the idea upon realizing that it'd mean mischief opportunities for his brothers.
