Romance comes at small cost but high opportunity cost

It's been a busy week for ah lun, as he only have a few hours sleep every day this week. Not to mention he has to work on the evening /midnight of Valentines' Day. As a rough calculation, we meet only 10-15 minutes per day.
He is not a very romantic person since I know him, but sometimes he could do some sweet tricks to cheer me up.
He came back home at 6AM on Friday morning, 13 Feb, and put the chocolates on the cabinet where i accessorize myself every morning. What a surprise for me when i wake up at 7AM! He got the chocolates from a hotel chocolate supplier based in Ap Lei Chau, so they are really in good quaility! it's funny to hear the delivery of these chocolates - he stick the box on the oil tank of the motorbike, because he is afraid that the chocolate will be crushed in his backpack.
In the midnight of 13 Feb, so I am giving him a surprise at no cost. The risk is burning my flat by myself (so you see the opportunity cost is really high). I pulled out all the tea light candles to make something nice.
I hope he likes the little surprise for him when he is back home at 4AM (I am in deep sleep leaving the candles on). He slept for 4 hours and went off to work this morning at 8AM on 14 Feb. This creative guy has sent me another sentence using the same amount of candles. I am really touched.
Since I wake up at 11am, some of the tea light candles are gone. Luckily, the fire department did not come to our flat at last. wakakakak :P

I think this is romantic because we are thinking of each other even though we have no time to meet up. The good news is he is off on Sunday, and we can have a belated celebration and a good meal at a reasonable price, instead of those high cost lousy couple set dinner.
