yeah, the picnic part on day 17 before you see her naked on day 18. Q's walkthrough goes a lil like this...
I can talk and then kiss both at 18:00 but then it skips to 20:00.
so your saying the kiss at 18:00 takes 2 hours? damn, hellova kiss eh? lol
ETA: ok, so tried it again. and yes, the kiss at that part does take 2 hours(damn son!). so I reversed the order and did the massage first and then the kiss and it worked out better. so if indeed the kiss length is correct at the picnic area, you may want to reverse those two steps in the walkthrough
